This site provides a definition for plane figure (at the top of the page) and a few examples.

In this activity, you will explore the invariant properties of rotations and the results of rotations in the coordinate plane.

In this activity, students will explore the properties of rotations and the relationships between the original and image figures.

Students, teachers, and parents alike will enjoy this challenging math site. It contains a clever brain teaser section plus creative problems related to algebra, geometry, measurement, numbers, statistics, and probability. A Spanish...

Step by step, this video lesson [4:34] will show you how to add up the number of squares that cover an object in order to find the area of a figure. It is 4 of 7 in the series titled "Finding Area with Squares."...

This article describes a new approach to teaching children more than just memorizing a formula to find area and hope they don't confuse it with perimeter. This approach involves a project with real life situations....

This interactive activity is designed for the student to review different geometric planes figures.

[Free Registration/Login may be required to access all resource tools.] The video describes how to determine what shapes are used to create a given composite shape. The video is followed by practice problems.

[Free Registration/Login may be required to access all resource tools.] The video defines a composite shape and shows how to determine the total number of triangles in the given shape. The video is followed by practice problems to assess...

In this video from Cyberchase, Bianca breaks her friend's tabletop when she's practicing dance moves in his living room. She uses measurement and geometry to get a new piece of wood that will fit the table exactly. The accompanying...

[Free Registration/Login Required] This flipchart discusses plane figures and solid figures.

A dilation is a transformation that produces a figure with a different size from that of the original figure. In this activity, you will explore the properties of dilations and the relationships between the original and image figures.

A rotation is a transformation that turns a figure a certain number of degrees about a certain point. This activity explores the properties of rotations and the relationships between the original and image figures.

View video footage from the scene of the plane accident that claimed the life of Polish President Lech Kaczynski, the first lady and key figures in the Polish Government. Was it pilot error, or that the Soviet-designed plane was more...

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

In this activity, students will explore the properties of dilations and the relationships between the original and image figures.

Students will explore the cross-sections that result when a plane cuts through a rectangular prism or pyramid. Students will also see examples of cross-section cuts in real-world situations.

This site includes an interactive math tool to create drawings on isometric dot paper. You can draw figures using edges, faces, or cubes. Rotate and color your drawings, and view them in 3D or 2D.

User will drag the vertices of the quadrilaterals to decide on the best possible classification.

[Free Registration/Login may be required to access all resource tools.] The video describes how to determine how many triangles are needed to create the complex composite shape.
