Triangle Similarity Theorems

Triangle ABC and Triangle PQR are constructed such that the two triangles have the same three angle measures.

You can drag vertex A or vertex C in triangle ABC. [br][br]What do you notice about the ratios of corresponding sides between the two triangles?[br]

You can drag vertex P or vertex R in triangle PQR.[br][br]What do you notice about the ratios of corresponding sides between the two triangles?

When moving a vertex of either triangle, what remained the same in each triangle?
