Geometric Model by A. Harry Wheeler, Line Perpendicular to Two Lines
name: label: Maker
content: A. Harry Wheeler
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. This plastic platform model shows the intersection of four planes. The green base serves as the platform and the other three intersect in a line perpendicular to the platform. The third plane (which is represented by a yellow triangle between a pink and a dark green triangle) is attached to the base along the perpendicular to the triangle fromed by the intersection of the base, the two side triangles, and the line joining the vertices of the two side triangles.It also is perpendicular to the vertical line of intersiceion of these triangles . Hence a line perpendicular to two lines.
