Dissertação (Mestrado em Matemática) - Universidade Federal de Goiás, Goiânia, 2013.http://repositorio.bc.ufg.br/tede/handle/tde/2996This work aimed to propose the use of the software GeoGebra - Operating System Linux - as a tool for di erentiated content of Plane Geometry for High School. The relevance of this research lies in the fact of being a GeoGebra software free access which makes it possible to carry out the activities proposed in this work in any school that has a laboratory computer basics. It is also believed that a tool can be GeoGebra useful for promoting a dynamic di erentiated classes of plane geometry, usually worked Just chalk on blackboard. This study proposes the use of software in 5 topics: Resolution equation of the second degree by the geometric method, Cycle Trigonometric; Baricentro; Arc capable and Ret golden angle. The research proved satisfactory, reaching the objectives set and con? Rmando the hypotheses. The realization of this work is also intended to call the re? Exon educators living with the paradigm of new technologies within schools. It is expected that reading text presented to stimulate the use of information technology resources for the greater good that is the constant pursuit of a quality education for our students.application/pdfAcesso abertoGeometria planaInformática educativaGeogebraPlane geometryMATEMATICA::MATEMATICA APLICADADissertação
