It is the relationship between sides and angles of non-right triangles.

Law of sines state that the ratio of length of the side of the non-right-angled triangle of the sine of the opposite angle of that side.

This is same for all angles and sides in an oblique triangle.

In a triangle ABC, the sides are a, b, and c, then

\(\displaystyle\frac{{a}}{{{\sin{{\left({A}\right)}}}=\frac{{b}}{{{\sin{{\left({B}\right)}}}=\frac{{c}}{{\sin{{\left({C}\right)}}}}}}}}\)
