Definitions are provided line of symmetry, line symmetry, and plane symmetry, and several nice examples are provided that illustrate these definitions.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and take an assessment on identifying and counting lines of symmetry in various shapes.

This study guide on the composition of transformations covers some vocabulary terms and different types of these compositions. It is available for download with free registration.

Students learn about geometry by investigating different shapes and their properties. Topics include plane geometry, drafting tools, transformations, angles, and trigonometry.

Great resource to practice and strengthen math skills pertaining to Geometry. Math worksheets are printable, may be customized, and include answer keys.

Use the Desmos transformation tools (link at top of page) to complete this scavenger hunt. There are three levels to choose from and solutions are included.

Investigate transformations through use of a graphing calculator and then using graph paper. This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.

Given an equilateral triangle, young scholars are asked to explore its symmetries using rigid transformations of the plane. Aligns with G-CO.B.

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

Test your knowledge of position, direction, and movement.

Over two dozen links are provided at this MathWorld site. From Polynomials and Series to Dynamical Systems and Catastrophe Theory, each link provides in-depth explanations and relevant diagrams of the topics at hand.

This one page website can expand your logic, Motion Geometry and pattern recognition knowledge. The solution is available to double check your answers.

Follow the directions at this one page website. You will get lots of practice plotting points on the coordinate grid and experience with transformational geometry.

Investigate dilations using this interactive resource. Students are given an opportunity to explore how scale factors can be used to enlarge or reduce the size of a given figure. Be sure to follow the link to the printable activities,...

Use the interactive transformation tool to perform dilations for four problems. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this exercise, students practice performing translations on a coordinate plane. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.
