Answer
$30^{\circ} = \frac{\pi}{6}$
$45^{\circ} = \frac{\pi}{4}$
$60^{\circ} = \frac{\pi}{3}$
$120^{\circ} = \frac{2\pi}{6}$
$135^{\circ} = \frac{3\pi}{4}$
$150^{\circ} = \frac{5\pi}{6}$
$180^{\circ} = \pi$
$210^{\circ} = \frac{7\pi}{6}$
$225^{\circ} = \frac{5\pi}{4}$
$240^{\circ} = \frac{4\pi}{3}$
$300^{\circ} = \frac{5\pi}{3}$
$315^{\circ} = \frac{7\pi}{4}$
$330^{\circ} = \frac{11\pi}{6}$
Work Step by Step
When the angle is stated in degrees, multiply by $\frac{\pi}{180}$. When the angle is stated in radians, multiply by $\frac{180}{\pi}$.
