Wheeler, Albert Harry

Description

This hinged dissection has two triangular pieces that may be arranged to form a triangle in two ways.

The three objects denoted by MA.304723.747, MA.304723.748, and MA.304723.749 together comprise six right triangles (hinged in pairs) which can be arranged as a single triangle divided into segments by perpendicular bisectors. Rearranged, they appear to form a quadrilateral.

The three objects together form model TE in Wheeler's list of decompositions of polygons.
