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

When we rotate something we turn it. In math, when we perform a rotation we turn a figure in a circular motion. This tutorial gives an explanation and examples of rotations. [3:51]

This video lesson defines and provides examples of the center of rotation for geometric figures. [1:55]

A video screencast demonstrating how the rotational inertia of an object depends on its mass and axis of rotation. [2:22]

Determine how to rotate a geometric figure across a coordinate plane in this video tutorial. [4:24] Then take a quiz to assess learning.

Explore how an object can rotate on a coordinate plane then assess learning with a quiz.

Rotational symmetry is introduced in this video tutorial. The lesson provides examples and students can check their understanding with an assessment. [2:58]

This video lesson [3:32] demsonstrates how to rotate geometric figures in the coordinate plane. Students can check their understanding with an assessment.

Explore how to rotate a geometric object across a coordinate plane with this video lesson. [10:37] Assess learning with a quiz.

Take a look at this tutorial to learn about rotations which are just circular movements. [3:51]

An animated video that explains rotations in transformational geometry. [1:44]

This tutorial shows you how to rotate coordinates from the original figure about the origin, then connect the points to create the new figure. Watch this video to see the process in action. [5:52]

This tutorial explains how to rotate coordinates from the original figure about the origins, then connect the points to create the new figure. [4:51]

This tutorial explains how to rotate coordinates from the original figure about the origin, then connect the points to create a new figure. [5:10]

Construction a rotation transformation in R3 around the x-axis.

Finally we'll need to rotate object to finish our scene.

Sal is given a triangle on the coordinate plane and the definition of a rotation about an arbitrary point, and he manually draws the image of that rotation.

An older video where Sal finds the images of shapes under various rotations, and where he determines the rotations that take one shape to another.

An older video where Sal uses the interactive widget to find the image of a line segment under a rotation.

An older video where Sal determines the rotation that takes one shape to another.

If you rotate a 2D shape about an axis, the shape will define a 3D object. Watch Sal rotating various 2D shapes and see what 3D objects he gets!

First let's think about how to rotate some really simple points such as (0,0) and (1,0) Click here to review basic trig ratios.

Sal Khan shows that there will be a net torque on a loop of current in a wire in this video. He also shows that this net torque will cause the loop to rotate. [10:35]

Demonstrates how to use an interactive tool to rotate a pentagon on a Cartesian grid. [1:25]
