Answer 1

Option (a) corresponding angles are equal AND corresponding sides are proportional is the correct answer.

Triangles are considered similar when corresponding angles are equal AND corresponding sides are proportional.

Answer 2

Choice a.

Explanation:

There is no such thing as proportional angles when it comes to similar triangles, so eliminate choices b and d. That leaves a and b.

If corresponding angles are congruent, the triangles are similar, and the lengths of corresponding sides will be proportional, so I go with choice a.
