Description:

This cut and folded paper model is one of several in which A. Harry Wheeler illustrated properties of polar spherical triangles. A sticker on it reads: PT*. One polar triangle is inside the other. The vertices are unlabeled. The model is undated and has no Wheeler number.

For a discussion of polar triangles, see MA.304723.159. Compare MA.304723.491, MA.304723.516, and MA.304723.521.
