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 base or platform, with other segments (often other rectangles) secured to it. These other pieces sometimes penetrated the platform.
label: Description
content: This tan paper platform model has a cream-colored base penetrated by two rectangles that intersect in a line perpendicular to the platform. Holles in the platform allow the rectangles to rotate about their line of intersection. A mark on the underside of the platform reads: Two Planes (/) Perpendicular to a Third Plane (/) A. Harry Wheeler (/) 1911.
