The law of sines is a basic trigonometric law concerning the relationship between angles and sides on a trianle in a flat plane. For any triangle having angles alpha, beta and gamma and respective opposite sides of a, b and c:
- <math>{\frac{a}{\sin \alpha}}={\frac{b}{\sin \beta}}={\frac{c}{\sin \gamma}}
