Platonic Solids - A Virtual Manipulative
A Platonic solid is a polyhedron whose faces are identical regular polygons. The ancient Greeks were able to show that there are exactly five such Platonic solids. This virtual manipulative allows you to display, rotate, and resize Platonic solids. It also allows you to select vertices, edges, and faces, and observe that the number of vertices minus the number of edges plus the number of faces is always equal to 2 (Euler's formula).
Platonic Solids - Slicing - A Virtual Manipulative
Discover shapes and relationships between slices of the platonic solids. This virtual manipulative displays a Platonic solid on the left and on the right the outlined cross-sectional slice formed by a plane cutting through the solid. There are more instructions to the right of the manipulative.
