Their respective products of distances are equal to each other and to the power of point P in that circle. This equality is sometimes known as the secant-tangent theorem , intersecting chords theorem , or the power-of-a-point theorem .here s is the distance between P and the center O of the circle. By this definition, points inside the circle have negative power, points outside have positive power, and points on the circle have zero power. For external points, the power equals the square of the length of a tangent from the point to the circle.
