Question

a transformation is rigid if which of the following occurs? option #1: the preimage and image are the same shape and size. option #2: the angles are the same but not the side lengths. option #3: the side lengths are the same but not the angle measures. option #4: the figures change shape but not size. (1 point) option #

Explanation:

A rigid transformation (isometry) preserves the shape and size of a figure. This means the pre - image and the image have the same shape and size, including the same side lengths and angle measures.

Answer:

Option #1: The preimage and image are the same shape and size.
