Build your own polygon and transform it in the Cartesian coordinate system. Experiment with reflections across any line, rotations about any point, and translations in any direction.

In this task, 8th graders are given the coordinates of a point and are asked to find the coordinates of its reflection across a line parallel to the x-axis. Aligns with 8.G.A.3.

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

Learners use the coordinate plane to investigate how reflections affect geometric shapes. Can be used by the student, but is also a great lesson plan idea for teachers.

The purpose of this task is to apply translations and reflections to the graphs of the functions f(x)=cos x and g(x)=sin x in order to derive some trigonometric identities. There are also rotations 180 degrees about points on the x-axis...

In this activity the teacher will send two lists, a window range, and an educational document via the TI-Navigator. Students will explore the reflections and rotations of a shape in the rectangular coordinate system.

[Free Registration/Login may be required to access all resource tools.] Transformations move and modify geometric shapes. There are several types of transformations that all transform figures in different ways. These transformations can...

In this activity, students will identify and record ordered pairs from a coordinate plane. They will examine symmetry about the axes, reflections, and symmetry in nature. They understand geometric concepts like area and perimeter, and...

In this lesson plan 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 activity is designed to reinforce the concepts of reflections and translations by having the students create a virtual puppet using Cabri Jr. As they construct their puppets, students will reinforce their understanding of...

A unique geometry project that asks students to complete a transformation using a picture. Project includes instructions, examples, and quiz questions.

This site offers a short discussion of transformations. The discussion has few pictures and expresses the transformations in terms of relative coordinates rather than pictures.

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...

This site gives some examples of line reflection transformations. Includes coordinate graphs to show reflections of lines and shapes.
