A definition and several examples of rotational symmetry. View two animations showing types of rotational symmetry, as well as real-life examples, including a dartboard and Ferris wheel.

[Free Registration/Login Required] Students will explore how to determine the coordinates of a rotated figure by adjusting the points on the line. Click challenge me to answer practice questions and click learn more to watch a video.

[Free Registration/Login may be required to access all resource tools.] Students watch a video to determine if given shapes have rotational symmetry and then take an assessment to test their skills.

Explains how to perform a rotation using an interactive tool and presents problems to try. Includes a video example. [1:25] Hints are available for the problems.

In this activity, students describe how to move a shape from one place to another in a plane. They learn about translations, rotations, and line reflections. [Requires Adobe Reader.]

Students are introduced to translations, reflections, and rotations and how to explore them in real-world scenarios.

This lesson focuses on symmetry including reflectional symmetry, rotational symmetry, and palindromes. It defines each, gives examples, and practice activities.

Test your knowledge of rotational symmetry.

Explore transformations of a polygon that include: 1) translation 2) rotation 3) reflection and 4) dilation.
