ABSTRACT:
A device and method for illustrating geometric shapes are disclosed which enables individuals to study and visualize the interrelation between geometric shapes and more particularly complementary geometric shapes such as tetrahedrons. The apparatus includes a plurality of tubes that pass through a central support member. Cords pass through the tubes, each cord having its ends connected, forming a closed loop. The tubes are movable within the support member. As the tubes are manipulated, the size and geometry of the visualized shapes are altered. In one embodiment, four tubes and three cords define two complementary tetrahedrons. When the tubes are manipulated to expand one tetrahedron, the complementary tetrahedron shrinks.
