Object Details
- 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 tan paper model shows the intersection of two triangles with a plane. One is a vertical right tiangle, perpendictular to the plane. The other rests on the hypotenuse of the first triangle. Drawn on the second triangle is a line that is perpendicular to a line on the base. A mark on the model reads: L(. . .)PL-L (. . .) L*. Here the characters (. . .) represent the symbol for perpendicular.
