Abstract

The trisection of the angle, together with the doubling of the cube and the quadrature of the circle, is among the three problems of antiquity formulated as early as the 5th century BC, known as the three classical problems of ancient mathematics. This paper deals with the approximate construction of the angle trisection, whose inaccuracy is approximately 0.1%. The simple design uses only rulers and compasses and is feasible in a small number of steps. The method simultaneously uses the properties of the finite sum of an infinite geometric series.
