MENELAUS' THEOREMS ON TRIANGLES AND THEIR NEW PROOFS
Keywords:
Menelaus' theorem, sine of an angle, similarity of a triangle, ratio of sections.Abstract
This paper presents new and easy-to-learn proofs of Menalay's theorems. This theorem is the key to many complex problems. In schools, lyceums and specialized boarding schools, studying mathematics is necessary and has a very important place in preparing a student for the Olympiad. Triangular similarity and the theorem of sines were used to prove Menelaus' theorem.
