Chapter 7 Review Geometry

For a dilation with a scale factor less than 1, how do the angles and side lengths of the preimage relate to the angles and side lengths of the image?

• Angles are congruent; side lengths are larger.

• Angles are congruent; side lengths are smaller.

• Angles are proportional; side lengths are larger.

• Angles are proportional; side lengths are larger.
