Question

Why is the information in the diagram enough to determine

that ALMN - APON using a rotation about point N and a
dilation?

Answer 1

Corresponding angles of similar triangles are congruent.

The true statement is (c) one pair of congruent corresponding angles is sufficient to determine similar triangles

From the complete question (see attachment), we have:

∠

∠NOP≅∠NML

This means that:

Angles NOP and NML are congruent

When the corresponding angles of similar triangles are congruent, then the triangles can be assumed to be similar.
