Geometric Model by A. Harry Wheeler, Regular Hexagon Transformable into Rhombus Transformable into Two Equilateral Triangles, Plane Dissection


These six quadrilateral pieces are hinged in threes. They may be arranged to form a parallelogram (in this case a rhombus), two equilateral triangles, or a regular hexagon.

A drawing of the model in 1979.3002.43, folder 2, is dated March 22, 1932. Another drawing of it is in 1979.3002.55. folder 1 and dated April 16, 1932
