Geometry power theorem
In elementary plane geometry, the power of a point is a real number that reflects the relative distance of a given point from a given circle. It was introduced by Jakob Steiner in 1826. Specifically, the power of a point with respect to a circle with center and radius is defined by WebPower of A Point Theorem. New Resources.
