Abstract

In this paper, we present some interesting inequalities for a triangle and a point inside the triangle.
At all events, the most well-known of these inequalities is the famous Erdös-Mordell inequality.
In 1935, Erdös published the inequality in the journal American Mathematical Monthly, and Mordell gave his proof in the same year.
This inequality as well as some interesting inequalities and their proofs are presented in this paper.

Keywords

inequalities, triangle, Erdös-Mordell’s inequality, inscribed circle, circumscribed circle
