I appreciate it, but I'm supposed to prove it using similar triangles, not congruent ones, so I don't think this will work.

triciaal · Answer

do you agree that similar triangles are congruent ?

sr16 · Answer

Well, I guess all congruent triangles are also similar, but not all similar triangles are congruent.. so maybe this will work. I was just thinking they were asking for triangles that are proportional to each other and have congruent angles, but are not the same size.

I just googles your question. These proofs are very old and I think this one was proved in elements (bc).
