Question

try it! 4. a. are these objects congruent? if so, describe a composition of rigid motions that maps one object onto the other.

Explanation:

Step1: Check for congruence

The two shapes have the same size and shape. So they are congruent.

Step2: Identify rigid - motion composition

First, rotate the left - hand shape 90 degrees clockwise about its center. Then, translate it to the right until it maps onto the right - hand shape.

Answer:

Yes, they are congruent. A 90 - degree clockwise rotation about the center of the left - hand shape followed by a translation to the right maps one object onto the other.
