• RST and TUV are alternate interior angles, and therefore congruent. RTS and UTV are vertical angles, and therefore congruent. Triangle RTS is similar to triangle VTU by the angle-angle criterion. Note: Two of the three angle statements must be stated for the student to get one point. 0 Student response is incorrect or irrelevant. Part B: Congruent Triangles. Triangles are congruent if they are the same shape and the same size. Because the size of the angles controls the shape of the triangle, in a pair of congruent triangles, you can match up angles that are the same size. In other words, corresponding angles are congruent.
