Geometric Model by A. Harry Wheeler, Two Lines with 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 platform, with other segments (often other rectangles) secured to it.

In this plastic model, thewhite rectangular base has white a rectangle perpendicular to it. Transparent green triangles are attached to the rectangles. A tag on the model reads: 2L (...) PL. Another tag reads: A. Harry Wheeler
