If the arc length across from an angle is less than 1 radius long, then the angle is less than 1 radians. If the arc length is longer than 1 radius, than the angle is more than 1 radians.

WebA radian is the standard unit of angle measure in mathematics and is defined such that a circle has 2π radians.
