Symmetrical Combinations of Three or Four Hollow Triangles

  • H. S. M. Coxeter

Abstract

A hollow triangle is the planar region bounded by two homothetic and concentric equilateral triangles, that is, a flat triangular “ring.” The edges of the inner triangle are half as long as those of the outer triangle. We will look at two striking constructions in three-space made from such figures.
