Practice questions

1 of 26Practice questions for this set

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?
