Olympiad Test: Congruence of Triangles - Question 1

 An angle of measure 180° is called

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 1

Option (c) is the correct answer.

An angle of measure 180° is called a straight angle.

Olympiad Test: Congruence of Triangles - Question 2

What is the side included between the angles A and B in ΔABC?

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 2

Angle A and Angle B have a line as AB , since we have two vertices A and B which gives us the side AB.

Olympiad Test: Congruence of Triangles - Question 3

In the below quadrilateral ABCD, AD = BC and ∠DAB = ∠CBA. If ΔABD ≌ ΔBAC. The relation between ∠ABD and ∠BAC is

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 3

In ΔABD and ΔBAC,

AD = BC (Given)

∠DAB = ∠CBA (Given)

AB = BA (Common)

∴ ΔABD ≅ ΔBAC (By SAS congruence rule)

∴ BD = AC (By CPCT)

And, ∠ABD = ∠BAC (By CPCT)

Olympiad Test: Congruence of Triangles - Question 4

In the quadrilateral ABCD, AC = AD and AB bisect ∠A and ΔABC ≅ ΔABD. The relation between BC and BD is

Olympiad Test: Congruence of Triangles - Question 5

In the below figure, AC and BD are equal perpendicular to line segment AB. If ?BOC ≅ ?AOD, then the relation between OC and OD is

Olympiad Test: Congruence of Triangles - Question 6

In the below figure, AB = AC = CD. If ΔACD ≌ ΔABE then AD =

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 6

ΔACD ≌ ΔABE. Here angle A corresponds to Angle A, Angle C with Angle B and Angle D with Angle E, Similarly Side AC corresponds to AB, CD to BE and AD to AE. So AE is the answer.

Olympiad Test: Congruence of Triangles - Question 7

ΔABC is right triangle in which ∠A = 90° and AB = AC. The values of ∠B and ∠C will be

Olympiad Test: Congruence of Triangles - Question 8

The measure of each angle of an equilateral triangle is:

Olympiad Test: Congruence of Triangles - Question 9

If the vertical angle of a isosceles triangle is 40°, then measure of other two angles will be

Olympiad Test: Congruence of Triangles - Question 10

If ∠A, ∠B and ∠C of ΔABC are equal, then triangle is

Olympiad Test: Congruence of Triangles - Question 11

Which one of the following is the value of congruency?

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 11

We have four congruence criterions namely, SSS,SAS,ASA,RHS. There is no such ASS or SSA criterions

Olympiad Test: Congruence of Triangles - Question 12

By which congruence rule following triangles are congruent ?

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 12

The SSS rule states that:

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Olympiad Test: Congruence of Triangles - Question 13

In the below figure, AC = BD and AD = BC. Which of the following statements is meaningfully written? 

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 13

AC corresponds to BD and AD corresponds to BC. So while writing the name of the triangles the alphabets should be written according to the correspondence. So ΔABC ≅ ΔBAD

Olympiad Test: Congruence of Triangles - Question 14

Which is the longest side in the triangle ABC right angled at B?

Olympiad Test: Congruence of Triangles - Question 15

Which is the longest side of a right triangle?

Olympiad Test: Congruence of Triangles - Question 16

What is the angle included between the sides PN and PM of ΔMNP?

Olympiad Test: Congruence of Triangles - Question 17

In triangles ABC and PQR, AB = 3.5 cm, BC = 7.1 cm, AC = 5 cm, PQ = 7.1 cm, QR = 5 cm and PR = 3.5 cm, then which of the following is true

Olympiad Test: Congruence of Triangles - Question 18

A triangle in which all three sides are of equal lengths is called _________.

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 18

Equilateral means having all sides equal .So Equilateral triangle has all of its 3 sides equal.

Olympiad Test: Congruence of Triangles - Question 19

In triangles ABC and DEF, AB = 7 cm, BC = 5 cm, ∠B = 50°, DE = 5 cm, EF = 7 cm, ∠E = 50°. By which congruence rule the triangles are congruent?

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 19

Given: AB = EF = 7 cm,

BC = DE = 5 cm and

∠B =∠E = 50°

Also,

A↔F,B↔E,C↔D

By using SAS congruence rule, it can be written as

∆ABC ≅ ∆FED

Olympiad Test: Congruence of Triangles - Question 20

In the below figure, A B = AC and AD is the bisector of ∠BAC , then the relation between ∠B and ∠C is

Detailed Solution for Olympiad Test: Congruence of Triangles - Question 20

AB=AC(given)
∠BAD=∠CAD(angle bisector)
AD=AD(Common)
2)∠ABD≅∠ADC(SAS)
3)∠B=∠C
(because ∠ABD≅∠ADC(SAS)
