Please guess and proof: Figure 1 placed rectangular pieces of paper ABCD and ECGF B, rectangular pieces of paper, C, G three points in a straight line, CE at the edge of CD, if M is connected to AF, AF DM, ME connection point, the relation between DM and ME, conjecture, and prove that you conclusion. Expansion and extension: (1) if the 'conjecture and proof' in the paper for a square piece of paper ABCD and ECGF square piece of paper, other conditions remain unchanged, while the relationship between DM and ME for DM=DE. (2) Figure 2 placed square piece of paper ABCD and ECGF to F square piece of paper, on the edge of CD, M is still the center of the AF test certificate, (1) the conclusion still holds.
