At first, we will deal points that were relevant and contributed to the development of trigonometry, the second time will be presented to demonstrate the law of sines and law of cosines, and finally the application of the laws thus showing its wide application. To develop this work a survey was conducted in printed and electronic sources, making a bibliographical survey.openAccessLei dos senosLei dos cossenosAplicabilidade das leisbachelorThesis
