Students learn about the terminology and formulas associated with polyhedrons. The learning resource consists of definitions, images, and examples.

The polyhedron is defined and illustrated. Links provided for related terms, everyday examples, challenging problems, more information. There is also an interactive checkpoint involving polyhedrons.

This site defines a convex polyhedron in terms of vectors and matrices. A table of examples, as well as an illustration, are given. This site has numerous links to related Math World sites.

Use this tool to see animated models of over 100 different types of polyhedra. There are five options for how they appear, and you can also see the net, 'explode' the solid so that the faces are separated, or drag it to rotate it...

This site is a personal site that discusses the popular polyhedron, the pyramid. It explains that by joining two pyramids you will get a dipyramid.

This is an exploration of polyhedron and may be used as a lesson plan. The site contains links to various crystals that are formed as polyhedron, and links to creating your own paper polyhedron. Other exciting related links on polyhedral...

This lesson focuses on polyhedra; a polyhedron (the plural is polyhedra) is a 3-dimensional solid object that is made up of polygons. Euler's Polyhedron Formula: In every polyhedron, the number of faces (F) plus the number of vertices...

This site not only defines what a polyhedron is, but it allows you to view each of the five regular polyhedra through an interactive exercise. After selecting which polyhedron you'd like to see, it will tell you its name and how many...

Interactive resources and activities dealing with properties and characteristic of the five polyhedrons and the sphere.

An introduction to a type of three-dimensional shape called a polyhedron. See examples and play with an interactive animation, showing the faces, vertices, and edges of pyramids, which are a type of polyhedron.

This in-depth paper examines the idea of convexity. Euclid's Elements, the first geometry textbook, assumed convexity without mentioning the term.

This MathWorld site shows pictures of polyhedra which can fill space. A discussion of these figures follows.

This site gives a description of platonic solids along with a visual representation of each of the five platonic solids. At the bottom of the page are links to cut-out-templates for each of the platonic solids. Be sure to follow the...

At this one page website a variety of polyhedra are shown. The challenge is to create the skeleton for each polyhedron and identify the needed materials. You can check your solution right at the website.

[Free Registration/Login Required] This flipchart describes the characteristics of polyhedrons and asks students to classify figures according to the number of vertices, faces, and bases of the figures.

Contains six examples of polyhedra nets (cube, tetrahedron, octahedron, dodecahedron, icosahedron, cubosctahedron).

[Free Registration/Login may be required to access all resource tools.] This study guide reviews how to classify polyhedra, Euler's formula, and regular polyhedra.

The University of Saskatchewan's Department of Mathematics and Statistics provides high school students with online tutorials and exercises on what they deem some of the most important topics in geometry: Triangles, and Circles and Other...
