Question

If one of the non-right angles in a right triangle is equivalent to an angle in another right triangle, what can you say about the two triangles? What does that mean about the sides of the triangles? Explain.

Answer 1

The triangles are similar, they aren't congruent (identical) though as we don't know if they share a common side

Answer 2

The triangles are similar by AAA. AAA however does not prove congruency. The side would be proportional.
