Angle Defect and Descartes' Theorem
Scott, Paul
Australian Mathematics Teacher, v62 n1 p2-4 2006
Rene Descartes lived from 1596 to 1650. His contributions to geometry are still remembered today in the terminology "Descartes' plane". This paper discusses a simple theorem of Descartes, which enables students to easily determine the number of vertices of almost every polyhedron. (Contains 1 table and 2 figures.)
