Power of a point P intersects the circle at A and B, the endpoints of the diameter. 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"". The power of a point is used in many geometrical definitions and proofs. For example, the radical axis of two given circles is the straight line consisting of points that have equal power to both circles. For each point on this line, there is a unique circle centered on that point
MRT Circle Line needs to be done in the future. "We abide by the government’s decision (to discontinue the project) but we also acknowledge that the MRT line 3 is critical to close all the loop. We hope that one day in the future, once the government’s fiscal position gets better, the government will consider this.", he added. MRT Circle Line The MRT 3, MRT Line 3 or MRT Circle Line is a proposed thirteenth rail transit line, the fifth fully automated and driverless rail system in Klang Valley area. If completed, this line would form the loop line of the Greater KL/Klang
