Geometric Model by A. Harry Wheeler, Perpendicular Planes


To show relationships among planes and angles, A. H. Wheeler designed a series of what he called platform models. All of these had a rectangular base or platform, with other segments (often other rectangles) secured to it. These other pieces sometimes penetrated the platform.

This plastic platform model has a cream-colored base with an orange rectangle penetrating it perpendicularly. The second piece is held on the bottom by yellow supports. It illustrates perpendicular planes.
