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.
The following diagrams show different examples of dilations with different centers of dilation and scale factors. Scroll down the page for more examples and solutions.
