the radian measure of a central angle in a circle is the proportionality constant between the arc length intercepted by that central angle and the radius of the circle (s = (r). This implies that there are 2( radians in a full circle, because the arc length around a full circle is the circumference: s = C = 2(r.

A curve is a part of the arc of a circle. It is limited at each end by the radii of the circle which form a central angle at the center of the circle. Curves are described by the following terms: A. Radius is the distance from a point on the curve to the center of the circle. B. Length. of curve is the linear measurement of the curve. C. Concavity

Unit circle properties will allow special angle and related angle trigonometric values to be found without the aid of a graphing utility. Degrees and radians are units of angle measure. A radian is the measure of the central angle that is determined by an arc whose length is the same as the radius of the circle.
