AA Criterion from Similarity Transformations Practice Test

Two triangles, MNP and QRS, are being tested for similarity. It is known that $$\angle M = \angle Q = 48°$$ and that triangle QRS can be obtained from triangle MNP through a sequence of similarity transformations. A student concludes that this information alone is sufficient to prove similarity using the AA criterion. What is the error in this reasoning?

Triangle JKL undergoes a similarity transformation consisting of a reflection across line m followed by a dilation with scale factor k > 0. The resulting triangle J'K'L' has $$\angle J' = 42°$$ and $$\angle K' = 85°$$. If a student wants to prove that triangles JKL and J'K'L' are similar using the AA criterion, what information about triangle JKL is sufficient?
