anonymous · Answer

well they are the same shape for a start
and corresponding sides are in the same proportion

anonymous · Answer

Ok, I know that they are the same shape, and I know how to cross multiply, but how do you get from the fact that they are the same shape, to that they are similar using proportions?  If you can draw how, I would understand it better.  Thanks!
