Transformations and Congruent Shapes

Reflection

• Is a transformation that slides the figure up, down, left, or right.

• Is a transformations that flips the figure over a given axis.

• Is a transformation that rotates the figure.

• Is a transformation that enlarges or reduces the figure. It creates similar shapes.
