Question

When completing a dilation, how do the

angles and side lengths of the preimage
relate to the angles and side lengths of the
image?

Answer 1

The angles do not change, but the side lengths can either be increased or decreased depending on the scaling factor used.

Explanation:

A dilation is a type of rigid transformations that involves either increasing or decreasing the dimensions of a given object with respect to a required factor.

The size of the angles of the preimage and image are congruent. This implies that the value of the angles are not affected by the process. But the side length of the image can be either longer or shorter than that of the preimage depending on the scaling factor used.
