Geometric Model by A. Harry Wheeler, Polar Spherical Triangles
Object Details
- Wheeler, Albert Harry
- 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, MA.304723.521, MA.304723.664, and MA.304723.665. This model is considerable larger than MA.304723.664.
- For pattern see 1979.3002.087.
