"In each part (a)-(d) below, some additional assumptions about the picture are given. In each problem, determine whether the given assumptions are enough to prove that the two triangles are similar; and if so, what the **correct correspondence of vertices is** (NOTE: this is related to the similarity statement... be sure that you are correctly identifying corresponding parts). If the two triangles must be similar, **identify a theorem**. If not, explain why not."
