RBSE Solutions for Class 7 Maths Chapter 9 Congruence of Triangles Ex 9.1 is part of RBSE Solutions for Class 7 Maths. Here we have given Rajasthan Board RBSE Class 7 Maths Chapter 9 Congruence of Triangles Exercise 9.1.

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.
