The largest angle bisection procedure

Metric Geometry 2019-10-01 v2 History and Overview

Abstract

The {\it largest angle bisection} procedure is the operation which partitions a given triangle, TT, into two smaller triangles by constructing the angle bisector of the largest angle of TT. Applying the procedure to each of these two triangles produces a partition of TT into four smaller triangles. Continuing in this manner, after nn iterations, the initial triangle is divided into 2n2^n small triangles. We prove that as nn approaches infinity, the diameters of all these 2n2^n triangles tend to 00, the smallest angle of all these triangles is bounded away from 00, and that, with the exception of TT being an isosceles right triangle, the number of dissimilar triangles is unbounded.
