Transforming polygons is an important application of coordinate geometry. Digitally-designed art, including graphics and video games, all rely on transformations of polygons in order to move figures and characters around the screen.
To perform a dilation on a coordinate plane, you need to know two pieces of information. First, you need to know the scale factor, or magnitude of the enlargement or reduction. Second, you need a center of dilation, or reference point from which the dilation is generated.
In this resource, you will investigate more properties of dilations.
