An applet is used to investigate the rotation symmetry of regular polygons.

Investigate tessellations using this interactive Learn Alberta math resource. Students will explore transformations, namely line symmetry, rotation symmetry, and translation occurring within a tessellated pattern. Be sure to follow the...

Use Glencoe's randomly generated self-checking quiz to test your knowledge of lines of symmetry and rotational symmetry. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click...

This presentation provides a tutorial on symmetry. In the tutorial, you will do the following: learn about geometric symmetry, explore line or reflection symmetry, explore rotation symmetry, and explore translation symmetry and frieze...

[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.

[Free Registration/Login may be required to access all resource tools.] For this learning module, students examine shapes to determine if they have rotational symmetry. Includes video demonstrating a sample problem [1:31] and a set of...

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are asked to look at 2D shapes and decide if they have rotational symmetry. Includes video demonstrating a sample problem and a set...

This multimedia Learn Alberta math resource looks at real world examples of transformations found throughout West Edmonton Mall. The accompanying interactive component asks students to predict transformations through looking at...

An explanation from Teachers Network of what rotational symmetry is along with some examples that show this.

This is a good site for elementary teachers to help educate students about symmetry by using pattern blocks. This link has multiple activities that the instructor could use including technological and standard activities.

Analyze various shapes according to their reflective and rotational symmetries. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Investigate the concept of symmetry at this test prep site. See detailed definitions and picture examples, answer the questions in the interactive practice pages, and do the classroom activity where students use a digital camera to...

This University of Regina site gives some history and definitions about translations and symmetry.

Suppose ABCD is a quadrilateral for which there is exactly one rotation, through an angle larger than 0 degrees and less than 360 degrees, which maps it to itself. Further, no reflections map ABCD to itself. What shape is ABCD? Aligns...

This task examines the rigid motions which map a rectangle onto itself. The emphasis here is on careful reasoning using the definitions of reflections and rotations. Aligns with G-CO.A.3.

Uses an egg to demonstrate the concept of axis of symmetry. Put your cursor over the picture to "move" around the egg. Offers links to related concepts, including Cartesian Ovals and Ovals of Cassini.

Dr. Math, in a reply to a student question, shows how to derive the equation of a parabola for situations when the line of symmetry is not || to one of the axes.

This site gives a definition of angle of rotation and provides some examples. There is also an interactive activity in which a JavaSketchPad page is provided for you to explore rotations. In addition, be sure to follow the links to...

In this instructional activity, students observe symmetry, geometric shapes, and angles in two Early American dances, and then choreograph their own dance with symmetrical figures. Media and teaching materials are included.

Use this internet lesson to explore different types of symmetry in nature. Learners examine line symmetry, rotational symmetry, and bilateral symmetry. An integrated math, language art, and art lesson. Acrobat Reader required.

The learning activity explores symmetry. Students combine mathematics and art as they investigate reflection and rotation symmetry.

This Math Forum site gives visual examples of rotation, translation, reflection, and glide reflection with background information about each. Also gives problems to work on concerning symmetry.
