Learn how similarity transformation is one or more rigid transformations (reflection, rotation, translation) followed by a dilation.

This lesson focuses on dilations, a dilation is a transformation that resizes a geometric shape, by making it bigger or smaller.

A transformation is a function that takes points in the plane as inputs and gives other points as outputs. You can think of a transformation as a rule that tells you how to create new points from old points.

Provides an explanation, examples, and a video lesson all related to the four common types of transformation. [1:00]
