### Standard Position for Angles:

2 angles with the same intitial and terminal sides.

### Greek Symbols used for angles:

• Alpha

• Beta

• Theta

• As well as uppercase A,B,C.

• 1 radian = measure of a central angle (θ), that intercepts an arc (s) = to the radius (r) of the circle.

### Sketching and finding “coterminal” angles:

Add or subtract 2 from angle
