I had to puzzle this out myself. In this case, we need to (a) find the center of dilation (b) verify that the dilation of A to A' is the same as that of B to B' Since dilation is a linear scaling, both A and B are moving toward some point C. Naturally, if the dilation ...

Dilation means expansion. If it is not mentioned about which point dilation occurs, it is about (0,0). In such a case (also the present case), dilation by a factor of k means multiply all x and y coordinates by k. For example, a point originally at (2,1) will be at (4,2) after...

Since 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...
