A system of measuring angles in radians, where the measure of an angle is defined by the ratio of the arc length to the radius of a circle.

  1. Angle measurement in radiansC1formal

    A system of measuring angles based on the radius of a circle, where one radian is the angle subtended at the center of a circle by an arc equal in length to the radius.

    • In circular measure, a full circle equals 2π radians.
    • The angle was expressed in circular measure rather than degrees.
    • Students learned to convert degrees to circular measure for calculus problems.
