Question

a transformation is applied to create a new figure on the coordinate grid. which type(s) of transformations preserve congruence?

Explanation:

Rigid - motions (translations, rotations, reflections) preserve congruence as they maintain the shape and size of the figure. Non - rigid motions like dilations change the size and thus do not preserve congruence.

Answer:

Translations, rotations, and reflections preserve congruence.
