Geometry Dilation

Examples, solutions, videos, worksheets, games, and activities to help Geometry students learn about transformations on the coordinate plane. In this lesson, we will look at dilations in geometry.

What is dilation in geometry?
A dilation is a non-rigid transformation, which means that the original and the image are not congruent. They are, however, similar figures. To perform dilations, a scale factor and a center of dilation are needed. If the scale factor is larger than 1, the image is larger than the original; if the scale factor is less than 1, the image is smaller than the original.

How to Dilate Objects On The Coordinate Plane?
This tutorial reviews how to dilate an object on the coordinate plane when the center of dilation is the origin and also when the center of dilation is not the origin.

Math Dilations
Students learn that when the dimensions of a figure are increased or decreased to create a new figure that is similar to the original figure, the transformation is called a dilation.
