Abstract: Using this virtual manipulative, the student can examine the five platonic solids, each a polyhedron with identical regular polygonal faces. The ancient Greeks discovered that there were five and only five such solids. The student can manipulate and change the size of each solid. A transparent mode is available for viewing the outline of each polyhedron. It is also possible to investigate the vertices, edges, and faces and apply Euler's formula. Instructions for using the applet, background information about the platonic solids, and a lesson plan are included. There is also a link to the NCTM standard for geometry.
