The curvature at each point of a line is defined to be 1/r, where r is the radius of the osculating, or “kissing,” circle that best approximates the line at the given point. The normal, or perpendicular, at each point of a surface defines the corresponding tangent plane, and vice versa. curved space-time intrinsic curvature of a surface
