Step 1
1 of 3

Let $ABC$ be a triangle with sides $a,b$ and $c$ opposite to its angles at its vertices $A, B$ and $C$, respectively. Then the Sine Law states that the three ratios of the length of a side to the sine of the angle opposite it are equal. Mathematically this is written as:

$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$
