Description:

Using this virtual manipulative, the student can examine the dual relationship among the five platonic solids, each a polyhedron with identical regular polygonal faces. Every platonic solid has a unique platonic solid that fits inside it, with its vertices at the midpoints of the original solid. The student can manipulate, color, and change the size of each solid. A transparent mode is available for viewing the outline of each polyhedron and its dual. Instructions for using the applet and information about platonic solids are included. There is also a link to the NCTM standard for geometry. Copyright 2005 Eisenhower National Clearinghouse
