1. Congruence of Triangles

2. Criteria for Congruence of Triangles

3. Some Properties of a Triangle

4. Inequalities in a Triangle

• Triangle – A closed figure formed by three intersecting lines is called a triangle. A triangle has three sides, three angles and three vertices.

·**•** **Congruent figures –** Congruent means equal in all respects or figures whose shapes and sizes are both the same for example, two circles of the same radii are congruent. Also two squares of the same sides are congruent.**•** **Congruent Triangles-** two triangles are congruent if and only if one of them can be made to superpose on the other, so as to cover it exactly.

• If two triangles ABC and PQR are congruent under the correspondence A ↔ P,B ↔ Q and C ↔ R then symbolically, it is expressed as DABC ≅ DPQR

• In congruent triangles corresponding parts are equal and we write ‘CPCT’ for corresponding parts of congruent triangles.**·• SAS congruency rule –** Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of the other triangle. For example: ΔABC and ΔPQR as shown in the figure satisfy SAS congruent criterion

**• ASA Congruence Rule –** Two triangles are congruent if two angles and the included side of one triangle are equal to two angles and the included side of other triangle. For examples ΔABC and ΔDEF shown below satisfy ASA congruence criterion.

• AAS Congruence Rule – Two triangle are congruent if any two pairs of angles and one pair of corresponding sides are equal for example ΔABC and ΔDEF shown below satisfy AAS congruence criterion.

• AAS criterion for congruence of triangles is a particular case of ASA criterion.

• **Isosceles Triangle –** A triangle in which two sides are equal is called an isosceles triangle.

For example: DABC shown below is an isosceles triangle with AB=AC.

• Angle opposite to equal sides of a triangle are equal.

• Sides opposite to equal angles of a triangle are equal.

• Each angle of an equilateral triangle is 60o .

• **SSS congruence Rule –** If three sides of one triangle are equal to the three sides of another triangle then the two triangles are congruent for example ΔABC and ΔDEF as shown in the figure satisfy SSS congruence criterion.

• ** RHS Congruence Rule – ** If in two right triangles the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle then the two

triangle are congruent. For example: ΔABC and ΔPQR shown below satisfy RHS congruence criterion.

RHS stands for right angle – Hypotenuse side.

• A point equidistant from two given points lies on the perpendicular bisector of the line segment joining the two points and its converse.

• A point equidistant from two intersecting lines lies on the bisectors of the angles formed by the two lines.

• In a triangle, angle opposite to the longer side is larger (greater)

• In a triangle, side opposite to the large (greater) angle is longer.

• Sum of any two sides of a triangle is greater than the third side.

**Answer**

B

**1. In triangles ABC and PQR, ∠A= ∠Q and ∠B = ∠R. Which side of ΔPQR should be equal to side AB of ΔABC so that the two triangles are congruent? Give reason for your answer.Sol.**

In triangle ABC and PQR, we have

∠A = ∠Q [Given]

∠B = ∠R [Given]

For the triangle to be congruent, we must AB = QR. They will be congruent by ASA congruence rule.

**2. In triangles ABC and PQR, ∠A= ∠Q and ∠B = ∠R. Which side of ΔPQR should be equal to side BC of ΔABC so that the two triangles are congruent? Give reason for your answer.****Sol.**

In triangle ABC and PQR, we have

∠A = ∠Q and ∠B = ∠R [Given]

For the triangles to be congruent, we must have

BC = RP

They will be congruent By AAS congruence rule.

**3. “If two sides and an angle of one triangle are equal to two sides and an angle of another triangle, then the two triangles must be congruent.” Is the statement true? Why?****Sol.** This statement is not true. Angles must be the included angles.

**4. “If two angles and a side of one triangle are equal to two angles and a side of****another triangle, then the two triangles must be congruent.” Is the statement true?****Why?****Sol.** This statement is true. Sides must be corresponding sides.

**5. Is it possible to construct a triangle with lengths of its sides as 4 cm, 3 cm and 7 cm? ****Give reason for your answer.****Sol.** We know that the sum of any two sides of a triangle is always greater than the third side.

Here, the sum of two sides whose lengths are

4 cm and 3 cm = 4 cm + 3 cm = 7 cm,

Which is equal to the length of third side, i.e., 7 cm.

Hence, it is not possible to construct a triangle with lengths of sides 4 cm, 3 cm and 7 cm.

**6. It is given that ΔABC ≅ ΔRPQ. Is it true to say that BC = QR? Why?****Sol.** It is False that BC = QR because BC = PQ as ΔABC ≅ ΔRPQ.

**7. It is given that ΔPQR ≅ ΔEDF, then is it true to say that PR = EF? Give reason for your answer.****Sol.** Yes, PR = EF because they are the corresponding sides of ΔPQR and ΔEDF.

**8. In ΔPQR, ∠P = 70° and ∠R = 30°. Which side of this triangle is the longest? Give reason for your answer.****Sol.** In ΔPQR, we have

∠Q =180^{0} − (∠P +∠R)

= 180^{0} − (70^{0} + 30^{0}) = 180^{0} − 100^{0} = 80^{0}

Now, in ΔPQR, ∠Q is the larger (greater) and side opposite to greater angle is longer.

Hence, PR is the longest side.

**9. AD is a median of the triangle ABC. Is it true that AB + BC + CA > 2 AD? Give reason for your answer.****Sol.** In ΔABD, we have

AB + BD > AD …(1)

[∵ Sum of the lengths of any two sides of a triangle must be greater than the third sides]

Now, in ΔADC, we have

AC + CD > AD …(2)

[∵Sum of the lengths of any two sides of a triangle must be greater that the third side]

Adding (1) and (2), we get

AB + BD + CD + AC > 2AD

⇒AB + BC +CA > 2AD [∵BD = CD as AD is median of ΔABC]

**10. M is a point on side BC of a triangle ABC such that AM is the bisector of ∠BAC. Is it true to say that perimeter of the triangle is greater than 2 AM? Give reason for your answer.****Sol.** We have to prove that

AB + BC + AC > 2AM.

As sum of any two sides of a triangle is greater than the third side, so in ΔABM, we have

AB + BM > AM …(1)

And in ΔACM, AC + CM > AM …(2)

Adding (1) and (2), we get

AB + BM + AC + CM > 2AM

Or AB + (BM + CM) + AC > 2AM

⇒ AB + BC + AC > 2AM

Hence, it is true to say that perimeter of the triangle is greater than 2AM.

**11. Is it possible to construct a triangle with lengths of its sides as 9 cm, 7 cm and 17 ****cm? Give reason for your answer.****Sol.** No, it is not possible to construct a triangle whose sides are 9cm, 7cm and 17cm because 9cm + 7cm = 16cm < 17cm Whereas sum of any two sides of a triangle is always greater than the third side.

**12. Is it possible to construct a triangle with lengths of its sides as 8 cm, 7 cm and 4 cm? Give reason for your answer.****Sol.** Yes, it is possible to construct a triangle with lengths of sides as 8 cm, 7 cm and 4 cm as sum of any two sides of a triangle is greater than the third side.

**1. ABC is an isosceles triangle with AB = AC and BD and CE are its two medians. Show that BD = CE.Sol.** Given: ΔABC with AB = AC

And AD = CD, AE = BE.

To prove: BD = CE

Proof: In DABC we have

AB = AC [Given]

⇒ (1/2)AB = (1/2)AC

⇒ AE = AD

[∵ D is the mid-point of AC and E is the mid-point of AB]

Now, in ΔABD and ΔACE, we have

ΔABD ≅ ΔACE

⇒ BD = CE [CPCT]

Hence, proved.

**2. In Fig .7.4, D and E are points on side BC of a Δ ABC such that BD = CE and AD = AE. Show that Δ ABD ≅ Δ ACE.**

**Sol. **Given: ΔABC in which BD = CE and AD = AE.

To Prove: ΔABD ≅ ΔACE

Proof: In ΔADE, we have

AD = AE [Given]

⇒ ∠2 = 1

[∵Angle opposite to equal sides of a triangle are equal]

Now, ∠1+∠3 =180 …(1)

[Linear pair axiom]

∠2 +∠4 =180 …(2)

[Linear pair axiom]

From equations (1) and (2), we get

∠1+ ∠3 = ∠2 +∠4

⇒ ∠3 = ∠4 [∵∠1= ∠2]

Now, in ΔABD and ΔACE, we have

AD = AE [Given]

∠3 = ∠4 [Proved above]

BD = CE [Given]

So, by SAS criterion of congruence, we have

ΔABD ≅ ΔACE

Hence, proved

**3. CDE is an equilateral triangle formed on a side CD of a square ABCD (Fig.7.5). Show that ΔADE ≅ ΔBCE.**

Sol. Given: An equilateral triangle CDE formed on side CD of square ABCD.

To prove: ΔADE ≅ ΔBCE

Proof: In square ABCD, we have

∠1 = ∠2 …(1) [∵Each = 90^{o}]

Now, in ΔDCE, we have

∠3 = ∠4 …(2) [∵Each = 60^{o}]

Adding (1) and (2), we get

∠1+ ∠3 = ∠2 +∠4

⇒ ∠ADE + ∠BCE

Now, in ΔADE and ΔBCE, we have

DE = CE [Sides of an equilateral triangle are equal]

∠ADE = ∠BCE [Hence proved]

AD = BC [Sides of a square are equal in length]

So, by SAS criterion of congruence, we have

ΔADE ≅ ΔBCE

Hence, proved

**4. In Fig.7.6, BA ⊥ AC, DE ⊥DF such that BA = DE and BF = EC. Show that Δ ABC ≅ Δ DEF.**

Sol. We have BF = EC

∴ BF + FC = CE + FC ⇒ BC = EF

In ΔABC, ∠A = 90^{0} and in ΔDEF,ÐD = 90^{0} .

∴ ΔABC and ΔDEF are right triangles.

Now, in right triangles ABC and DEF, we have

BA = DE [Given]

And BC = EF [Proved above]

∴ ΔABC ≅ ΔDEF [By RHS congruence rule]

**5. O is a point on the side SR of a ΔPSR such that PQ = PR. Prove that PS > PQ.Sol. **Given: PQ = PR

To prove: PS > PQ

Proof: In ΔPRQ, we have

PR = PQ [Given]

⇒ ∠1 = ∠R

[∵Angles opposite to equal side of triangle are equal]

But, ∠1 > ∠S

[∵Exterior angle of a triangle is greater than each of the remote

interior angles]

⇒ ∠R > ∠S [∵∠1= ∠R]

⇒ PS < PR [∵ In a triangle, side opposite to the large is longer]

Hence, proved.

**6. S is any point on side QR of a ΔPQR. Show that: PQ + QR + RP > 2 PS.Sol.** Given: A Point S on side QR of ΔPQR.

To prove: PQ + QR + RP > 2PS

Proof: In ΔPQS, we have

PQ + QS > PS …(1)

[∵ Sum of the length of any two sides of a triangle must be greater than the third side]

Now, in ΔPSR, we have

RS + RP > PS …(2)

[∵ Sum of the length of any two sides of triangle must be greater than the third side]

Adding (1) and (2), we get

PQ + QS + RS + RP > 2PS

⇒ PQ + QR + RP > 2PS

Hence, proved.

**7. D is any point on side AC of a ΔABC with AB = AC. Show that CD < BD.****Sol.** In ΔABC, we have

AB = AC [Given]

∴ ∠ABC = ∠ACB

[∵ Angles opp. To equal sides of a triangle are equal]

Now, ∠DBC < ∠ABC

∴ ∠DBC < ∠ACB or ∠DBC < ∠DCB

Hence, CD > BD. [∵ Side opposite a greater angle is longer]

**8. In Fig. 7.7, l||m and M is the mid-point of a line segment AB. Show that M is also the mid-point of any line segment CD, having its end points on l and m, respectively.**

Sol. In ΔAMC and ΔBMD, we have

∠1 = ∠3 [Alt. ∠s because l||m]

∠2 = ∠4 [Vert. opp. ∠s ]

AM = BM [Given]

∴ DAMC ≅ DBMD [By ASS congruence rule]

∴ CM = DM [CPCT]

Hence, M is also the mid-point of CD.

**9. Bisectors of the angles B and C of an isosceles triangle with AB = AC intersect each other at O. BO is produced to a point M. Prove that ∠MOC = ∠ABC.****Sol.** Bisector of the angles B and C of an isosceles triangle ABC and AB = AC intersect each other at O. BO is produced to a point M.

In ΔABC, we have

AB = AC

∴ ∠ABC = ∠ACB

[∵Angles opposite to equal sides of a triangle are equal]

⇒ 1/3 ∠ABC = 1/2 ∠ACB

i.e., ∠1 = ∠2 [∵BO and CO are bisectors of ∠B and ∠C ]

In ΔOBC, Ext. ∠MOC = ∠1+ ∠2

[∵ Exterior angle of a triangle is equal to the sum of interior opposite angles]

⇒ Ext. ∠MOC = 2∠1

Hence, ∠MOC = ∠ABC.

**10. Bisectors of the angles B and C of an isosceles triangle ABC with AB = AC intersect each other at O. Show that external angle adjacent to ∠ABC is equal to ∠BOC.****Sol.** In ΔABC we have

AB = AC

∴ ∠B = ∠C [∵Angles opposite to equal sides of a triangle are equal]

∴ 1/2 ∠B = 1/2 ∠C …(1)

In ΔOBC,we have

∠ = 1/2 ∠B

And ∠2 = 1/2 ∠C

∴ ∠1 = ∠2 [By (1)]

∠DBC + ∠1 + ∠OBA = 180^{0 } [∵ ABD is a straight line]

⇒ ∠DBC + 2∠1 =180^{0} [∵ ∠1 = ∠OBA] …(1)

In ΔOBC,

∠1 + ∠2 + ∠BOC = 180^{0}

⇒ 2 ∠1 + ∠BOC = 180^{0 } [∵ ∠1 = ∠2] …(2)

From (1) and (2), we get

∠DBA + 2 ∠1 = 2 ∠1 + ∠BOC

⇒ ∠DBC = ∠BOC

**11. In Fig. 7.8, AD is the bisector of ∠BAC. Prove that AB > BD.**

**Sol.** Since exterior angle of a triangle is greater than either of the interior opposite angles, therefore, in ΔACD,

Ext ∠3 > ∠2⇒ ∠3 > ∠1

[∵ AD is the bisector of ∠BAC, so ∠1 = ∠2 ]

Now, in ΔABD, we have

∠3 > ∠1

Hence, AB > BD. [∵ In a triangle, side opposite to greater angle is longer]

**1. Find all the angles of an equilateral triangle.****Sol.** In ΔABC,we have

AB = AC

⇒ ∠C = ∠B …(1)

[∵ Angles opposite to equal sides of a triangle are equal]

BC = AC

⇒ ∠A = ∠B …(2)

[∵Angles opposite to equal sides of a triangle are equal]

Now, 0 ∠A + ∠B + ∠C = 180^{0 } [∵ Angle sum property of a triangle]

⇒ ∠A+∠A+∠A =180^{0} [From (1) and (2)]

⇒ 3∠A =180^{0}

⇒ ∠A = 180^{0}/3 = 60^{0}

∠A = ∠B = ∠C = 60^{0}

**2. The image of an object placed at a point A before a plane mirror LM is seen at the point B by an observer at D as shown in Fig. 7.12. Prove that the image is as far behind the mirror as the object is in front of the mirror.**

**Sol.** Let AB intersect LM at O. We have to prove that AO = BO.

Now, ∠i = ∠r …(1)

[∵Angle of incidence = Angle of reflection]

∠B = ∠i [Corres. ∠s] …(2)

And ∠A = ∠r [Alternate int. ∠s ] …(3)

From (1), (2) and (3), we get

∠B = ∠A

⇒ ∠BCO = ∠ACO

In ΔBOC and ΔAOC we have

∠1 = ∠2 [Each = 90^{o}]

OC = OC [Common side]

And ∠BCO = ∠ACO [Proved above]

∴ ΔBOC ≅ ΔAOC [ASA congruence rule]

Hence, AO = BO [CPCT]

**3. ABC is an isosceles triangle with AB = AC and D is a point on BC such that AD⊥BC** **(Fig. 7.13). To prove that ∠BAD = ∠CAD, a student proceeded as follows:**

**In ΔABD and ΔACD,****AB = AC (Given)****∠B = ∠C (because AB = AC)****and ∠ADB = ∠ADC****Therefore, ΔABD = ΔACD (AAS)****So, ∠BAD = ∠CAD (CPCT)****What is the defect in the above arguments?****[Hint: Recall how ∠B = ∠C is proved when AB = AC].****Sol.** In ΔABD and ΔADC, we have

∠ADB = ∠ADC [∵Each equal to 90o]

AB = BC [Given]

AD = AD [Common side]

So, by RHS criterion of congruence, we have

ΔABD ≅ ΔACD

∴ ∠BAD = ∠CAD [CPCT]

Hence, proved.

**4. P is a point on the bisector of ∠ABC. If the line through P, parallel to BA meet BC at Q, prove that BPQ is an isosceles triangle.Sol. **We have to prove that BPQ is an isosceles triangle.

∠1 = ∠2 …(1)

[∵ BP is the bisector of ∠ABC ]

Now, PQ is parallel to BA and BP cuts them

∴ ∠1 = ∠3 [Alt. ∠s ] …(2)

From (1) and (2), we get

∠2 = ∠3

In ΔBPQ we have

∠2 = ∠3 [Proved above]

∴ PQ = BQ [∵Side of opp. To equal angles are equal]

Hence, BPQ is an isosceles triangle.

**5. ABCD is a quadrilateral in which AB = BC and AD = CD. Show that BD bisects both the angles ABC and ADC.****Sol.** In ΔABC and ΔCBD, We

AB = BC [Given]

AD = CD [Given]

BD = BD [Common side]

∴ ΔABC ≅ ΔCBD [By SSS congruence rule]

⇒ ∠1 = ∠2 [CPCT]

And ∠3 = ∠4

Hence, BD bisects both the angle ABC and ADC.

**6. ABC is a right triangle with AB = AC. Bisector of ∠A meets BC at D. Prove that BC = 2 AD.Sol.** Given: A right angles triangle with AB = AC bisector of ∠A meets BC at D.

To prove: BC = 2AD

Proof: In right ΔABC,

AB = AC [Given]

⇒ BC is hypotenuse

[ ∵Hypotenuse is the longest side.]

∴ ∠BAC = 90^{0}

Now, in ΔCAD and ΔBAD we have

AC = AB [Given]

∠1 = ∠2 [∵AD is the bisector of ∠A]

AD = AD [Common side]

So, By SAS criterion of congruence, we have

ΔCAD ≅ ΔBAD

∴ CD = BD [CPCT]

⇒ AB = BD = CD …(1)

[∵Mid-point of hypotenuse of a rt. D is equidistant from the

three vertices of a D ]

Now, BC = BD + CD

⇒ BC = AD + AD [Using (1)]

⇒ BC = 2AD

Hence, proved.

**7. O is a point in the interior of a square ABCD such that OAB is an equilateral triangle. Show that Δ OCD is an isosceles triangle.****Sol.** Given: A square of ABCD and OA = OB = AB.

TO prove: ΔOCD is an isosceles triangle.

Proof: In square ABCD,

∠1 = ∠2 …(1)

[∵Each equal to 90^{o}]

Now, in ΔOAB , we have

∠3 = ∠4 …(2)

[∵Each equal to 60^{o}]

Subtracting (2) from (1), we get

∠1−∠3 = ∠2 −∠4

⇒ ∠5 = ∠6

Now, in ΔDAO and ΔCBO,

AD = BC [Given]

∠5 = ∠6 [Proved above]

OA = OB [Given]

So, By SAS criterion of congruence, we have

ΔDAO ≅ ΔCBO

∴ OD = OC

⇒ ΔOCD is an isosceles triangle.

Hence, proved.

**8. ABC and DBC are two triangles on the same base BC such that A and D lie on the opposite sides of BC, AB = AC and DB = DC. Show that AD is the perpendicular bisector of BC.****Sol.** Given: ΔABC and ΔDBC on the same base BC. Also, AB = AC and BD = DC.

To prove: AD is the perpendicular bisector of BC i.e., OB = OC

Proof: In ΔBAD and ΔCADwe have

AB = AC [Given]

BD = CD [Given]

AD = AD [Given]

[common side]

So, by SSS criterion of congruence, we have

ΔBAD ≅ ΔCAD

∴ ∠1 = ∠2 [CPCT]

Now, in ΔBAO and ΔCAO, we have

AB = AC [Given]

∠1 = ∠2 [Proved above]

AO = AO [Common side]

So, by SAS criterion of congruence, we have

ΔBAO ≅ ΔCAO

∴ BO = CO [CPCT]

And, ∠3 = ∠4 [CPCT]

But, ∠3+∠4 =180^{0} [Linear pair axiom]

⇒ ∠3+∠3 =180^{0}

⇒ 2∠3 =180^{0}

⇒ ∠3 = 180^{0} / 2 = 90^{0}

∴ AD is perpendicular bisector of BC [∵BO = CO and ∠3 = 90^{0}]

Hence, proved.

**9. ABC is an isosceles triangle in which AC = BC. AD and BE are respectively two altitudes to sides BC and AC. Prove that AE = BD.****Sol.** In ΔADC and ΔBEC we have

AC = BC [Given] …(1)

∠ADC = ∠BEC [Each = 90o]

∠ACD = ∠BCE [Common angle]

∴ ΔADC ≅ ΔBEC [By SSS congruence rule]

∴ CE = CD [CPCT] …(2)

Subtracting (2) from (1), we get

AC – CE = BC – CD

⇒ AE = BD

Hence, proved.

**10. Prove that sum of any two sides of a triangle is greater than twice the median with respect to the third side.****Sol.** Given: ΔABC with median AD.

To prove:

AB + AC > 2AD

AB + BC > 2AD

BC + AC > 2AD
