Question 8

Sample Response: Dilations produce similar figures because the image and pre-image will have congruent corresponding angles. The corresponding side lengths of the figures will be proportional based on the scale factor. The shape is preserved and the sides are enlarged or reduced by the scale factor.

Revolt · Accepted Answer

Dilations produce similar figures because the transformation preserves the shape of the original figure while changing its size. The corresponding angles of the image and pre-image remain congruent, and the corresponding side lengths are proportional based on the scale factor. Because it satisfies both conditions for similarity—congruent angles and proportional sides—the resulting image is always similar to the pre-image.
