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:
Solution
In ΔABD and ΔCDB
AB = CD ...(Given)
AD = BC ...(Given)
BD is common
By SSS congruency
ΔABD ≅ ΔCDB
