The __________ is the ratio of a length of the image to the corresponding length on the original figure.

• reduction
• enlargement
• scale factor
• center of dilation

CCSS.7.G.A.1

A scale factor of less than one means

• that the prime image will be larger than the pre-image.
• That the prime image will be the same as the preimage.
• That you need to subtract that amount off  of each side.
• That the prime image will be a reduction of the preimage.
