Samed Jahangir Aliyev, Shahin M. Aghazade, Goncha Z. Abdullayeva


Areas are actively used in the solution of many geometrical problems. In this work,
smart and laconic solutions are found for various problems by means of the area method. The well-known trigonometric addition formula is also proved. In the area method, the given formulas are divided into the parts, whose areas are then calculated using problem data.
