Polar relations of real triangles and tetrahedra

Abstract

In the note "Polar Relations of Imaginary Triangles and Tetrahedra," we showed that these relations are identical to those defined by a known imaginary ellipse or ellipsoid, with neither passing through the given points. However, from the principles set forth in that note, it follows that definite polar relations of real triangles and tetrahedra may exist. This work constitutes a natural continuation of the preceding note, but pertains to triangles and tetrahedra taken as real.
