- Description
- 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 white plastic platform model shows the intersection of four planes. One serves as the platform and the other three intersect in a line perpendicular to the platform. The third perpendicular plane is represented by a triangle between two other triangles representing perpendicular planes. The line at the base of this central triangle is perpendicular to the line joining the two upper triangles and to the line joining the endpoints of the two other perpendicular triangles. Hence a line perpendicular to two lines.
