Geometric Model by A. Harry Wheeler, Two Parallel Planes and a Line Perpehdicular to Them
name: label: maker
content: Wheeler, Albert Harry
notes: label: Description
content: 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, two parallel rectangles are held apart by two intersecting rectangles. The line of intersection of the intersecting rectangles is perpendicular to the parallel rectangles.
label: Description
content: A paper tag on the model reads: 2 II PL - L [. . .]. The text in brackets is a symbol for perpendicular. Another paper tag reads: A. Harry Wheeler.
