Geometry DilationVideos, worksheets, games and acivities to help Geometry students learn about transformations on the coordinate plane. In this lesson, we will look at dilation.
Dilations 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.
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.
