Solution

Yes, ΔJKL and ΔMNP are similar. The similarity postulate that applies is the Angle-Angle (AA) postulate. This is because two pairs of corresponding angles are congruent (∠𝐾≅∠𝑁 and ∠𝐿≅∠𝑃), which is enough to say that the triangles are similar by the AA postulate. The lengths of the sides are not necessary for this postulate. So, the correct answer is A. Similar - AA.

Visualization, Reasoning and Proof, and SimilarityYou can show that two triangles are similar when certain relationships exist betweentwo or three pairs of corresponding parts. If you know two triangles are similar, thenyou know their corresponding sides are proportional.Task 1In the diagram below, AC 6 DF 6 BH and CB 6 FE.A DC GBHFEa. Find four similar triangles.
