radius of curvature. n. (Mathematics) the absolute value of the reciprocal of the curvature of a curve at a given point; the radius of a circle the curvature of which is equal to that of the given curve at that point. See also centre of curvature.
The radius of a circle is any line segment from the center of the circle to any point on the circle. The diameter of a circle is any line segment that passes through the center of the circle and has its endpoints on the circle. In any circle, the length of a diameter is twice the length of a radius. Radius and diameter are also used to name length. For example, the radius of the circle is 2 inches and the diameter is 4 inches.
