(Proceedings pages 507–508)


Physical models are invaluable aids for visualizing concepts clearly in space. In this paper mat board built more stable physical models. Polygons, polygon corners, and polyhedra are used to present a physical proof of regular solids. A physical proof shows five and only five regular corners, and subsequently five regular solids.
