Geometric transformations

This course is a part of 8th grade, a 7-course Topic series from Khan Academy.

In this topic you will learn how to perform the transformations, specifically translations, rotations, reflections, and dilations and how to map one figure into another using these transformations.

This course contains 7 segments:

Transformations intro

Identify transformations, including translations, rotations, reflections, and dilations.

Translations

Learn about transformations and how to perform them.

Rotations

Learn about rotations and how to perform them.

Reflections

Learn about reflections and how to perform them.

Properties & definitions of transformations

Let's continue our deep voyage through the world of transformations! Use your knowledge about the precise descriptions of the rigid transformations and their properties in various situations.

Dilations

In addition to the three rigid transformation, there are the dilations, which expand or shrink figures while keeping the same proportions. These are extremely important in the subject of Similarity! Gain experience by performing dilation, learn how to find the dilation that maps a given figure to another, and learn how to manually draw the image of a dilation.

Congruence and similarity

Learn about congruence and similarity, specifically as they relate to transformations. Learn to dilate shapes.
