Final answer:
To prove the congruency of triangles ∆KLM and ∆NMP, show that their corresponding sides and angles are equal. We can use the side-side-side (SSS) congruence criterion to determine their congruency.
Step-by-step explanation:
To prove that triangles ∆KLM and ∆NMP are congruent, we need to show that their corresponding sides and angles are equal. Given KL = NM, KM = NP, and LM = MP, we can see that the three sides of both triangles are equal in length.
Since the three sides of triangles ∆KLM and ∆NMP are equal, we can conclude that by the side-side-side (SSS) congruence criterion, the triangles are congruent.
