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. These other pieces sometimes penetrated the platform.This tan paper platform model shows a rectangular base and a vertical rectangle perpendicular to it. A line in the horizontal plane is perpendicular to the line of intersection of the two rectangles and to another line in the vertical plane. Parts of two other vertical planes are indicated by triangular pieces on either side of the central rectangle.
