Triangle pqr is similar to triangle tuv. the perimeter of triangle pqr is 60 inches. what is the perimeter of triangle tuv?

I'm assuming you don't know the definition of similarity, which is fine, but I want to clarify just in case you don't: Similarity is when two figures are the same in angles ONLY, and their sizes are proportional. Given this, PQR has a side 20" and TUV's respective side is 6". Now, there's a ratio: 20:6 Now, would you agree that it would then be logical that the perimeter would follow the same ratio? Where 60:P(TUV)? Hope this helps some!
