Transforming polygons is an important application of coordinate geometry. Graphics designers, video game producers, and computer animation artists all use coordinate transformations, including dilations, translations, and reflections, to generate digitally-designed art.

In this resource, you will investigate coordinate transformations, including dilations, translations, and reflections.

**Dilations** are transformations that generate an enlargement or a reduction.

**Translations** are congruence transformations that move an object, without changing its size or shape. Usually, a coordinate plane is used in order to track the location of the object.

**Reflections** are congruence transformations that generate a mirror image of an object, without changing its size or shape.
