## Rajasthan Board RBSE Class 7 Maths Chapter 9 Congruence of Triangles Ex 9.1

Question 1

If triangle ∆ABC is congruent to triangle ∆PQR then (RBSESolutions.com) write all corresponding congruent parts of triangle.

Solution:

∆ABC is congruent to ∆PQR therefore these two triangles are equal in shape and si∠e.

∴ In ∆ABC and ∆PQR

∠A = ∠ P, ∠B = ∠Q and ∠C =∠R

side AB = side PQ, side BC = side QR and side CA = side RP.

Question 2

If ∆LMN ≅ ∆XYZ then write those (RBSESolutions.com) parts which corresponds to following :

(i) ∠N,

(ii) LM,

(iii) ∠M,

(iv) MN

Solution:

(i) ∠N is corresponding angle to ∠Z.

(ii) Side LM is corresponding to side AT,

(iii) ∠M is corresponding angle to ∠Y.

(iv) Side MN is corresponding to side YZ.

Question 3

Fill in the blanks :

(i) Two line segment (RBSESolutions.com) are congruent if their ………… is equal.

(ii) Two squares are congruent if their …………… are equal.

(iii) In two congruent triangle, ∆PQR ≅ ∆ABC, ∠P measures 60° then ∠A measure …………

Solution:

(i) Length

(ii) sides

(iii) 60°

Question 4

Where you can be seen congruent figures (RBSESolutions.com) in daily life? Write any two examples.

Solution:

(i) Our parents or brother or sister have similar mobiles which are same in size and shape.

(ii) We see 100 – 100 rupee notes in purse of our father which are same in size and shape.

Question 5

Select congruent angles in the diagram given below (Identify by tracing the angles)

(Can you identify the congruence (RBSESolutions.com) of angles with the compass? Do it.)

Solution:

∠ABC ≅ ∠ONM, ∠PQR ≅ ∠MLK, ∠XYZ ≅ ∠RST.

To check the congruency of angles with the help of compass as we construct a 60° angle with the compass, similarly can check the following angles as:

we see that at the point of intersection (RBSESolutions.com) of both arcs, ∠B = ∠N, ∠Y=∠S and ∠Q = ∠L are equal to each other.
