To prove that triangles ΔLMN and ΔVTU are similar using the AA (Angle-Angle) Similarity Theorem, you need to demonstrate that two pairs of corresponding angles in the triangles are congruent. Therefore, the most appropriate response would be:
Show ∠L≅∠V and ∠M≅∠T.
If you can confirm that these two pairs of angles are congruent, then by the AA Similarity Theorem, you can conclude that ΔLMN ∼ ΔVTU.
