For any triangle, the Law of Sines (also called the Sine Rule) says:

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

In other words,

It helps us solve some triangles.

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

In other words,

**a side's length divided by the sine of the opposite angle**is the same for all three sides.It helps us solve some triangles.
