Learn how to determine the amount and direction of rotations of geometric figures. Also, learn about rotational symmetry.
- Notes on Rotations - Notes from the presentation on rotations.
- Shodor Interactive Rotation Activity - A great activity allowing you to choose one of three different shapes, choose the center of rotation as well as the magnitude of rotation, and see what the result is.
- A webpage by Mathisfun.com - This webpage by Mathisfun.com does a great job explaining rotational symmetry and giving several examples of rotational symmetry. A must-see to understand rotational symmetry.
- Rotation Explanation - An in-depth explanation of what rotation of a figure means.
- How do you rotate a figure?
- How can you figure out the amount of rotation of a figure?
- What is rotational symmetry?
- How do you know what type of rotational symmetry a figure has?
