The Law of Sines proves a relationship in a triangle between the angles and sides.

A Triangle can be made if aSinB=bSinA. The law of Sines is usually used in mathematics to find angles of a general triangle. If two sides and a angle are given, then this can be used to find a second angle. With being given the measurements of two sides and an angle, this could result in one or two triangles.

Johannes von Muller was the one who was discovered the Law of Sines. Muller was born I January 3, 1752, in a small town in lower Franconia (Dukedom of Coburg).

Triangles are a part of our everyday life, whether you notice them or not. A compass also requires knowledge of Sines. When your lost your need to know what direction you are going, what direction you were supposed to go, how many degrees off...
