The law of sines can be used to compute the remaining sides of a triangle when two angles and a side are known—a technique known as triangulation.
It can also be used when two sides and one of the non-enclosed angles are known.
"The ratio of the sine of an angle in a triangle to the side opposite that angle is the same for each angle in the triangle." These equal ratios are called the Law of Sines.
Notice that the Law of Sines must work with at least two angles and two respective sides at a time.
Simply, it states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle.
In ΔABC is an oblique triangle with sides a,b and c , then asinA=bsinB=csinC .
