Description:

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.
