sort of power of a pointLet \overline{PA} and \overline{PC} be tangents from P to a circle. Let B and D be points on the circle such that B, D, and P are collinear. Prove that AB \cdot CD = BC \cdot DA. Batman shows Superman his new phone. Batman"Alfred, whats the temperature in London?" Alfred"Just a second, sir."
