Abstract

I n the article “Another Theorem for Congruence of Triangles” by Kasi Rao Jagathapu [1], published in At Right Angles, March 2023, the author points to the need for formulating additional congruence theorems. (See also [2].) It may be useful to look at this question from a trigonometric point of view. Suppose we are given two sides of a triangle and one of the angles. Under what circumstances do these parameters uniquely fix the triangle? We consider the different possibilities.
