Two of the corresponding angles and the included sides of two triangles are congruent. Which statement must be true regarding the triangles?

They are similar. If two of the corresponding angles are the same, the third one is corresponding. If a triangle angles are, 60, 60, 60, that adds up to 180 ... but if a triangle's angles are, 60,60, 50, that is impossible. All angle measures must add up to 180*.
