Question

which transformation is a rigid transformation?

Explanation:

A rigid transformation preserves the size and shape of a figure. This means that the lengths of the sides and the measures of the angles remain the same. In the given options, we need to look for a transformation where the pre - image and the image have congruent side lengths and angle measures.

Answer:

The transformation where the corresponding sides and angles of the pre - image (triangle DEF) and the image (triangle D'E'F') are congruent is the rigid transformation. Without specific labels on which transformation is which among the options, we can't point to a specific one by name, but the one with congruent side - lengths and angle - measures is the rigid transformation.
