Ptolemy's theorem sample problems
WebAn Astronomer in Ancient Times. Claudius Ptolemy (about 85–165 CE) lived in Alexandria, Egypt, a city established by Alexander the Great some 400 years before Ptolemy’s birth. Under its Greek rulers, Alexandria cultivated a famous library that attracted many scholars from Greece, and its school for astronomers received generous patronage. 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.
