Combining Dilation and Translation

Introduction

Have you ever zoomed in on a picture and then moved it to a new spot on your screen? In math, that is similar to combining a dilation and a translation. These transformations help us understand how shapes can...

Transcript

Emma is doing math homework where she needs to transform trapezoid ABCD using two transformations: a dilation followed by a translation.

First, she dilates the trapezoid about the origin with a scale factor of 2. This means she multiplies each x-coordinate and each y-coordinate by 2.

So, A(-2, -1) becomes A'(-4, -2), ...
