7.6 Similarity TransformationsDilation: transformation that enlarges or reduces
a figure proportionally
Image: figure after the dilation
Preimage: original figure
Scale Factor of a Dilation: ratio of a length of the image to a corresponding length in the preimage
Center of Dilation: fixed point used for measurement when creating a dilation
image length preimage length
Distance Formula:
