Question

What do you know about the scale factor for the dilation shown? Explain.

Answer 1

The scale factor is some number between 0 and 1 (not including either endpoint) because the image is smaller than the preimage.

Triangle ABC is the preimage, or the "before"; while triangle A'B'C' is the image, which is the "after".

preimage ----> image

before ----> after

Answer 2

Sample Response: The scale factor is between 0 and 1 because the image is a reduction of the pre-image.
