In an isometric transformation, the preimage and image must not
a. change size
b. rotate
c. preserve angle measures
d. reflect across the -axis

The figure being transformed is called the preimage, pre- meaning before. In this case, the resulting image after transformation is called D.image. The figure after transformation retains the size and shape, except for the location and coordinates of the points. Hence the answer is A, change size
