name: label: maker
content: Wheeler, Albert Harry
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.

label: Description
content: In this cut and folded paper model, two intersecting planes can rotateabout their line of intersection. Their motion is limited by two parallel planes that are perpendicular to the line of intersection.
