A transformation is applied to a figure to create a new figure on the coordinate grid.
Which type(s) of transformation preserve(s) congruence? Explain your reasoning.
Sample answer.
A translation, reflection and rotation are all types of transformation that preserve
congruence. When you slide, flip, or spin a figure, a congruent figure is created.
The corresponding angle measures and corresponding side lengths between the
pre-image and image are equal.
