National Museum of American History

Object Details

Wheeler, Albert Harry
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.
