In this lesson on transformations and congruence, 8th graders will investigate dilations, rotations, reflections, and translations on the coordinate plane and the figures that result from these transformations.

This task provides students a chance to experiment with reflections of the plane and their impact on specific types of quadrilaterals. Aligns with 4.G.A.3.

This site defines transformation and lists several different examples of transformations. Be sure to follow the links to related terms, everyday examples, challenging problems, more information, and the interactive check point involving...

Included here are illustrations of reflections from a plane mirror, a concave mirror and a convex mirror.

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.]

Given a pair of figures in the coordinate plane, try to map one onto the other and determine whether they are congruent. Includes examples of glide reflections. Students receive immediate feedback and have the opportunity to try...
