Help with two column proof of a trapezoid
I have been asked to do a two column proof for a trapezoid. I am stumped on what to do. I am homeschooled and I am using a tough curriculum so the book I have for geometry assumes you know how to do everything or figure it out on your own. I would really appriciate some help please!!
question: Given: ROSE is a trapezoid with bases OS and RE.
Prove, OI • RI = EI • SI
and this is supposed to be a two column proof. :)
Thank you very very much!!

Minnie if you do not understand these clues ask for more help.
