To prove that triangles ΔLMN and ΔVTU are similar using the AA (Angle-Angle) Similarity Theorem, you need to show that two pairs of corresponding angles in the triangles are congruent.
The correct choice from the options provided is:
Show ∠L≅∠V and ∠M≅∠T.
This demonstrates that there are two angles in triangle LMN that are congruent to two angles in triangle VTU, which satisfies the AA Similarity Theorem, thus proving that ΔLMN∼ΔVTU.
