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
Circle line party mentioned in several newspapers. On 31 May, the night itself, thousands of people attended, the largest Circle line party ever. Some dressed in costumes ranging from 1920s prohibition figures to Boris Johnson himself. The line was suspended after several trains were damaged during the party, and a number of London Underground staff and police officers were assaulted.
