Polygon ABCD is dilated, rotated, and translated to form polygon A′B′C′D′. The endpoints of AB are at (0, -7) and (8, 8), and the endpoints of A'B' are at (6, -6) and (2, 1.5). What is the scale factor of the dilation?

Question

Polygon ABCD is dilated, rotated, and translated to form polygon A′B′C′D′. The endpoints of AB        are at (0, -7) and (8, 8), and the endpoints of A'B'         are at (6, -6) and (2, 1.5). What is the scale factor of the dilation?

anonymous · Answer

The scale factor 1/2 because the length of A'B' is half of that of AB
