Question

which of the following is true about translations? a they are a useful way to make a figure larger or smaller. b they sometimes require changing the shape of a figure. c they can help you see if two figures are congruent. d they involve spinning a figure around the origin.

Explanation:

Translation is a rigid - motion transformation. It moves a figure without changing its size, shape, or orientation. By translating one figure to coincide with another, we can check for congruence. Option A is about dilation, option B is incorrect as translation doesn't change shape, and option D is about rotation.

Answer:

C. They can help you see if two figures are congruent.
