Find Angle Measure in Degrees or Radians from Rotation on Coordinate Plane

A unit of angle of measure based on the length of a radian. It's the arc length divided by the radius.

When given a radian or degree over the amount to go around a circle, you can find another point by adding or substratcing a whole circle
