I wrote that proof, last year in a tutorial. The link: http://assets.openstudy.com/updates/attachments/565bceb0e4b0b09ed5de4edc-owlcoffee-1448857315716-remake.pdf The proof is located in page 4.

Utilizing that proof, you can also deduce that the opposite sides of a parallelogram are congruent, since I prove that the four triangles defined by the diagonals are congruent.

Now, I think you'll have to use other information, because I think I use this theorem.
So you'll have to re-think some of the steps, but it will give you a way to start it out.
