WebPtolemy, Latin in full Claudius Ptolemaeus, (born c. 100 ce—died c. 170 ce), an Egyptian astronomer, mathematician, and geographer of Greek descent who flourished in Alexandria during the 2nd century ce. In several fields his writings represent the culminating achievement of Greco-Roman science, particularly his geocentric (Earth-centred) model of … WebPtolemy's Theorem states that the product of the diagonals of a cyclic quadrilateral (a quadrilateral that can be inscribed in a circle) is equal to the sum of the products of the …
WebPtolemy's Theorem. This is described in the body of the proof of Theorem 2. (Sub- sequently, we found another proof of Theorem 1 that does not use Ptolemy's Theo- rem [3]). It turns out that, unlike in Theorem 1, none of the points of the parallelogram used in the proof of Theorem 2 need be exterior to the circle. THEOREM 2. WebPtolemy’s theorem: For a cyclic quadrilateral (that is, a quadrilateral inscribed in a circle), the product of the diagonals equals the sum of the products of the opposite sides. If the …
