Wheeler, Albert Harry
Description
The four pieces of this hinged dissection have plastic attached to both sides and a wooden central core. The pieces form an equilateral triangle with an inscribed rectangle which transforms into a parallelogram with an inscribed square.
This is a special case of Wheeler's model 4K (trapezoid into a triangle) in his list of decompositions of polygons.
