Question

which of the following is not a rigid motion transformation? a. dilation b. translation c. reflection d. rotation

Explanation:

Rigid - motion transformations preserve distance and shape. Translation, reflection, and rotation are rigid - motion transformations as they keep the size and shape of the figure the same. Dilation changes the size of a figure by a scale factor, so it is not a rigid - motion transformation.

Answer:

A. Dilation
