Law of Sines

Angles in a generic triangle

The "Law of Sines" can be used to calculate the angles of a triangle.

Law of cosines

The "Law of Sines" can be expressed as

a / sin A = b / sin B = c / sin C                         (1)


a, b and c = length of sides in triangle (m, ft ...)

A, B and C = angles in the triangle (degrees)
