Geometric Model by A. Harry Wheeler, Pentagon Transformable into Square Transformable into Hexagon, Plane Dissection


The fifteen pieces of this dissection fit into a pentagonal box with a wooden base, plastic sides and top, and paper lining. The pieces can be arranged as a regular pentagon, a square or a regular hexagon.

The pattern is first in 1979.3002.43 (folder 1).

Drawings of triangle-square-pentagon (14 pieces), triangle-square-pentagon-hexagon (26 pieces), square-pentagon-hexagon (15 pieces), triangle-square-hexagon (13 pieces)dated December 21, 1931 are in 1979.3002.43, folder 3.

This model apparently is not on Wheeler's list of decompositions of polygons.
