A New Look at the Fundamental Triangle Inequality
TL;DR: In this paper , a simple proof of the fundamental inequality of the triangle based on calculation of the cosine of an angle in one particular triangle formed from familiar centers is given, for the term which appears in the inequality, given a bound as a rational expression in terms of and .
