Geometric Model by A. Harry Wheeler, Regular Hexagon Transformable into Two Six-Pointed Stars, Plane Dissection

Description:

The seven pieces of this plane dissection may be arranged as a regular hexagon or as two equal stars (or, as Wheeler puts it, two intersecting equilateral triangles). The central star is red. The six outer rhombuses are hinged in pairs, making this a partially hinged dissection. Everything fits in a transparent green plastic case.

A drawing of this model, dated April 5, 1932, is in 1979.3002.55 (folder 1).

This is model 7HE in Wheeler's list of dissections under "Regular Hexagons." See 1979.3002.43 (folder 2).
