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:
उत्तर
In the given figure AC and BD bisect each other at O.
∴ OA = OC ...(Given), OB = OD ...(Given)
∠AOB = ∠COD ...(vertically opposite angles)
By SAS congruency
