In the diagram, AB, BC, CD, DE, EF, FG, GH, and HK all have length 4, and all angles are right angles, with the exception of the angles at D and F. If perpendicular EM is drawn from E to DF, and if x is the length of EM, then what is x^2? There are supposed to be pictures, but I didn't include them. Just makes it harder for you. :P
