Geometric Model by A. Harry Wheeler, Polar Spherical Triangles (incomplete)

Description:

This cut and glued clear plastic model is one of several in which A. Harry Wheeler illustrated properties of polar spherical triangles. A sticker on it reads: PT. An inner polar triangle and one arc of an outer one survives – two faces are missing. The vertices are unlabeled. The model is undated and has no Wheeler number.

For a discussion of polar triangles, see 304723.159. Compare 304723.491, 304723.516, 304723.521, and 1979.0102.212.
