When a set of coordinates on a preimage is multiplied by -n instead of n, the coordinates of the image rotate about the center o
f dilation by 180°. Consider all the potential intervals of n in the table. Enter information in the table to indicate whether the scale factor produces an enlargement, a reduction, or no size change. Also indicate whether the image rotates 180° about the center of dilation.
The value of n determines whether the image is bigger or smaller than the preimage. If 0 < n < 1, the image is smaller than the preimage. If n = 1, the image is the same size as the preimage: the two are congruent. If n > 1, the image is larger than the preimage.
