Mangbetu art shows the use of all four geometric transforms: Reflection, Translation, Rotation, and Scaling. This website will provide you with some cultural background on the Mangbetu and their art. The software will allow you to...

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.

[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 exercise, students determine whether two polygons are similar. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.

This lesson is an introduction to transformation and symmetry by showing examples in nature and in buildings.

[Free Registration/Login may be required to access all resource tools.] In this lesson students explore geometric dilations. Students examine guided notes, review guided practice, watch instructional videos and attempt practice problems.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students learn to dilate a figure. Students examine guided notes, review guided practice, watch instructional videos and attempt practice problems.

In this seven-problem quiz/practice, students show they understand the result of combining different transformations.

A transformation is a function that takes points in the plane as inputs and gives other points as outputs. You can think of a transformation as a rule that tells you how to create new points from old points.

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...

[Free Registration/Login may be required to access all resource tools.] In this lesson students recognize dilations and use scale factor to determine measurements. Students examine guided notes, review guided practice, watch...

This lesson focuses on symmetry in physics. The laws of nature are the name given collectively to the physical rules (usually expressed as mathematical equations) that try to explain everything we observe in the universe.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to draw dilated figures in the coordinate plane and use dilated figures in the coordinate plane to find scale factors. Students...

[Free Registration/Login may be required to access all resource tools.] In this lesson, students dilate figures in the coordinate plane. Students examine guided notes, review guided practice, watch instructional videos and attempt...

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

[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.

Practice reflecting points across axes on the xy coordinate plane. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Using Cabri Jr. and the properties of rotations to get a true understanding of how a figure is rotated about a point.

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.

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

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.

In this set of questions, students use an interactive tool to rotate objects on a Cartesian grid. Help is available through hints and videos.

Find the reflection that maps a given figure to another and draw the image of a reflection. The lines of reflection in this exercise have a wide range of slopes. Students receive immediate feedback and have the opportunity to try...

Given two figures on the coordinate plane, find the formal definition of the translation that takes one figure to another. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or...
