Abstract
U ovom radu dokazujemo osam novih nejednakosti za trokut. Te nejednakosti se temelje na jednoj dvostrukoj algebarskoj nejednakosti koju dokazujemo u teoremu 1. U dokazima koristimo više raznih jednakosti koje se odnose na elemente trokuta. Neke od tih jednakosti su dobro poznate.In this paper we prove eight new inequalities for a triangle. These inequalities are based on a double algebraic inequality that we prove in Theorem 1. In the proofs we use a variety of equalities related to
elements of a triangle. Some of these equalities are well known
