NCERT Solutions for Class 7 Maths Chapter 7 Congruence Ex 7.2 12

Solution:

We have ∆PQR and ∆TSU

PQ¯¯¯¯¯¯¯=SU¯¯¯¯¯¯¯ (Given)

PR¯¯¯¯¯¯¯=ST¯¯¯¯¯¯ (Given)

∠Q = ∠S (Given)

∠P = ∠T (Given)

∠R = ∠U (Given)

Since non of the criteria of congruence is relevant here.

∴ ∆PQR and ∆TSU are not congruent.
