I don't get the process of writing coordinate proofs. I'd like to have some work to show, but, unfortunately, I don't. Sorry about that.
Here's the problem in question, in case it helps with an explanation...
The Given is that Rectangle ABCD has the vertices A (0,4), B (6,4), C (6,0), and D (0,0). E is the midpoint of line segment DC, and F is the midpoint of line segment DA.
I need to prove that the area of Rectangle DEGF is 1/4th the area of Rectangle ABCD.
