Callum Mcintyre · Answer 1

a rotation, followed by a translation; and a translation, followed by two reflections

Explanation:

The types of transformations that preserve congruence are called isometries, or rigid transformations.

These transformations are: translations, reflections and rotations.

These only move or turn a figure, but do not change the size of it.

A dilation, however, will stretch or shrink a figure; this does not preserve congruence.
