For each part below, decide if the triangles are similar. If they are similar, use their similarity to solve for . If they are not similar, explain why not.

  1. The triangles share a common angle and parallel lines have congruent corresponding angles, so the triangles are similar by .

  2. Is there enough information to prove that the triangles are similar?


    Vertical angles are equal, so .
    Parallel lines have equal alternate interior angles, so .
    Triangles are similar by .
