Question

Consider the given pairs of triangles and say whether each pair is that of congruent triangles. If the triangles are congruent, say ‘how’; if they are not congruent say ‘why’ and also say if a small modification would make them congruent:

Sum

Solution

In ΔPQR and ΔABC

PQ = AB ...(Given)

RQ = BC ...(Given)

ΔABC is not congruent to ΔPQR.

If PR = AC then ΔABC ≅ ΔPQR
