Geometric Model by A. Harry Wheeler, Symmetrical Spherical Triangles, Each Separated into Three Isoceles Spherical Triangles


This cut and folded tan paper model shows two spherical triangles symmetrically located on opposite side of a sphere (only a great circle of the sphere is shown). Both of the spherical triangles are divided into three isoceles spherical triangles.

The model is among those Wheeler dubbed collapsible.
