**Steve**, Wednesday, March 7, 2012 at 1:30pmSince dilation is linear, if we extend the lines A-A1 and B-B1 to their intersection, we find that the center of dilation is

C = (-27/7,-3/5)

So,

CA = 13.66

CA1 = 10.49

scale = 10.49/13.66 = 0.76

check to make sure that B->B1 is dilated by the same amount:

CB = 9.49

CB1 = 7.26

scale = 7.26/9.49 = 0.76
