Geometric Model by A. Harry Wheeler, Line Perpendicular to a Plane

<< >>
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 platform, with other segments (often other rectangles) secured to it. This paper model has two perpendicular rectangles with two intersecting lines drawn on the vertical rectangle and one line (perpendicular to the intersection of the planes, meeting the intersection point of the other lines) drawn on the base. A mark on the model reads: Line Perpendicular (/) to a Plane (/) A. Harry Wheeler (/) 1916.
