Dissertação (Mestrado em Matemática em Rede Nacional) - Universidade Federal de Goiás, Goiânia, 2021.http://repositorio.bc.ufg.br/tede/handle/tede/11438We will approach in general, the content of trigonometry studied in high school, highlighting the trigonometric properties, definitions and problem situations involving the sine, cosine and tangent trigonometric ratios. We will also make a relationship between theory and practice involving hypothetical and everyday problems, working with mathematical models, geometric representations. We will use the GeoGebra software as a support tool for the construction of graphs and geometric figures, highlighting some properties and examples.Attribution-NonCommercial-NoDerivatives 4.0 InternationalRazões trigonométricasCírculo trigonométricoGeoGebraTrigonometric circleGeoGebraTrigonometric ratiosCIENCIAS EXATAS E DA TERRA::MATEMATICADissertação
