Geometric Model by A. Harry Wheeler, Two Perpendicular Planes

<< >>
Usage conditions apply
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 green base with a purple rectangle perpendicular to it, held by a clear plastic support. It illustrates perpendicular planes.
