Dilation—more than just an eye opener! A short video introduces the concept of dilating a figure given a center and a scale factor. Using prime notation, the installment of a larger geometry playlist shows how to label dilated images.

Multiply coordinates to either shrink or enlarge a figure. An informative segment of a geometry playlist introduces dilation on the coordinate plane. The dilations in the resource use the origin as the center of dilation, which makes...

Viewers learn how to identify and perform a variety of transformations with a video that provides seven items on transformations. Pupils demonstrate their understanding of dilations, reflections, rotations, and translations. The video...

Give your class a solid foundational understanding of transformations. The instructor in a concept video describes each type of transformation and transformation notation. He also identifies the types of transformations that...

Help learners recognize the characteristics of a quadratic graph and how changes affect them. An informative video uses a graphing calculator in order to find out what happens when the leading coefficient of a quadratic...

A transformation is the process of changing the graph of a figure or a shape. The instructor introduces the four most common transformations: reflection, dilation, rotation, and translation. So watch as she draws the transformations on a...

A dilation increases or decreases the size of a figure. In this lesson the teacher shows you how to use a scale factor of three to dilate the given figure. She identifies the ordered pairs, multiplies them by three, plots the new...

Models how to solve integer problems on absolute value and on the dilation of a triangle. [4:25]

Demonstrates how to plot a triangle on a Cartesian grid after a dilation and with a scale factor of 1/2. [2:26]

Transformations allow you to change or move a figure. Learn about all the different kinds of transformations by watching this tutorial. [4:18]

When someone's eyes dilate, their pupils get bigger or smaller, but they always stay the same shape. Dilation in math is very similar. When you dilate a figure, you change the size of the figure without changing its shape. This tutorial...

Transformations allow you to change or move a figure. Learn about all the different kinds of transformations by watching this video. [4:19]

Dilation allows you to shrink or enlarge the size of a figure without changing its shape. In this tutorial, you will learn how it's done. [3:50]

When you dilate a figure, you change the size of the figure without changing its shape. This tutorial introduces you to dilation. [8:38]

In this lesson, you will learn how to determine if two figures are similar by using dilations and scale factors. [5:23]

Planet Nutshell Math Shorts provide animated videos that explain various math topics. On this site, students learn about dilations.

Determining the center of dilation, given a figure and its image under a dilation.

Sal shows how we can use dilations to map a line into another, parallel, line.

Chefs at Gaines Street Pies explain how they make their pizzas and why all of their pizzas are similar circles. [4:13]

Dilation transformations are explored and related to translations and reflections in this video lesson. [3:12]

Demonstrates how to use a unit circle on a coordinate grid to prove that all circles are similar. [1:34]
