Triangle man, doing the things a triangle can!

Sharon,

You'll need to tell us what corollary 4.4 says in your textbook (as well as the original theorem that it is a corollary to) for anyone to be able to answer this question. Theorems and their corollary don't follow a universal numbering scheme.

Once you've told us what you want to try to prove then we can help you.
