I can convert between degree and radian measures for angles on the unit circle.

1
Angles can be measured in degrees or radians, with 360 degrees equivalent to 2π radians.
2
To convert from degrees to radians, divide by 180 and multiply by π, and to convert from radians to degrees, divide by π and multiply by 180.
3
Coterminal angles are angles that share the same terminal side and differ by a multiple of 2π radians or 360 degrees.
