What is Degree of the Curve?

The curvature of a circular arc is perfectly defined by its radius. However, where the radius is long (highways) the center of the curve is inaccessible or remote. In such a case the radius is of no value for surveying operations, though still needed in certain computations; it must be replaced by a different characteristic of the curve which is most useful. The characteristic commonly used is known as degree of curve.
Midpoint: It is the summit or apex of the curve.
Apex distance: The distance from the point of intersection to the apex of the curve.
Central angle: The angle subtended at the center of the curve by the arc.
