Abstract

At the International Mathematical  Оlympiads, many complex geometric  identities are used to solve geometric problems. In particular, these equations take the form of a trigonometric sum or multiplication of the angles of a triangle. Basically, these equations are proved by difficult geometric constructions. Below we give these proofs by using the cubic equation method.
