Q1 of 45 Page 31

In each of the examples given below, a pair of triangles is shown. Equal parts of triangles in each pair are marked with the same signs. Observe the figures and state the test by which the triangles in each pair are congruent.

: By SSS congruency test

ΔABC ≅ ΔPQR


Explanation:


Given, AB = PQ


BC = QR


CA = RP


∴ By SSS congruency test


ΔABC ≅ ΔPQR


SSS : Side Side Side
