O Teorema de Ptolomeu e aplicações

Abstract

The present work shows a brief history of Cl ´audio Ptolemeu and his contributions to mathematics, astronomy and other areas of knowledge. Then we made some state- ments of his theorem through the original demonstration, his generalization made by Casey and other statements. Finally we have a few applications in which Ptolemeu’s theorem is inserted from which we get the Pit ´agoras theorem as a result of Ptolemeu’s theorem showing the importance of their application in the teaching of mathematics. For the realization of this work was done a literature in written and electronic sources.
