on . Posted in Trigonometry

The ratio of the sine of any angle within any specific triangle and the length for the opposite side is a constant.

## Law of Sines Formulas

$$\large{ \frac {sinA}{a}=\frac {sinB}{b}=\frac {sinC}{c} }$$

or three separate equations:

$$\large{ \frac {sinA}{a}=\frac {sinB}{b} }$$

$$\large{ \frac {sinA}{a}=\frac {sinC}{c} }$$

$$\large{ \frac {sinB}{b}=\frac {sinC}{c} }$$
