ON TRIGONOMETRIC PROBLEMS STUDIED IN GEOMETRY
Keywords:
trigonometric problem, equivalent ratios, cheviana, set of chevianas, median, bisector, height.Abstract
The article presents methodological results on the transversal lines and the basic concepts derived from them, which are important in solving trigonometric problems studied in geometry, in particular, the trigonometric representation of the main elements of a triangle. At the same time, the application of equivalent ratios and their genetic aspects in solving trigonometric problems studied in geometry are presented.
