Geometric Model by A. Harry Wheeler, Equilateral Triangle with Inscribed Rectangle or Parallelogram with an Inscribed Square, Plane Dissection

Description:

The four pieces of this hinged dissection have plastic on both sides and a wooden core. They can be arranged as an equilateral triangle or a square.The pieces on one side have smaller plastic parts on them so that the equilateral triangle appears to have an inscribed rectangle.

This is a special case of Wheeler's model 4K (trapezoid into a triangle) in his list of decompositions of polygons.
