1. which transformation(s) preserve congruence?

Explanation:

Step1: Recall congruence - preserving transformations

Rigid - motions (isometries) preserve congruence. These include translations, rotations, and reflections.

Step2: Analyze the nature of transformations

Translations move every point of a figure the same distance in the same direction. Rotations turn a figure around a fixed point. Reflections flip a figure over a line. Dilations change the size of a figure and do not preserve congruence.

Answer:

Translations, rotations, and reflections.
