Revisiting Mat Board Models for A Physical Proof of Five and Only Five Regular Solids or Polyhedron
(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.
