Transformations

A type of transformation where a figure is “flipped” over a line of symmetry. A reflection produces a mirror image of a figure.

 one type of transformation where a geometric figure is “slid” horizontally, vertically, or both. Sliding a polygon to a new position without turning it. When translating a figure, every point of the original figure is moved the same distance and in the same direction
