Some historic aspects are approached about the appearance of Geometry and the discussion about the Fifth Postulate of Euclides. We will demonstrate known results and important ones like Pitagora's Theorem and the addition of internal angles of a triangle. We will also demonstrate some results considered as true, even if its demonstrations are not well known, like all "triangles are a convex polygon". Lastly, some interesting results of Triangle Geometry are demonstrated that are no broadly disclosed between students and teachers, like Euler's straight, the circumference of the nine points, Ceva's and Menelau's theorems and Stward's relation. It is waited that this work serves as source of research for students and teachers, and that it also motivates them to be constant researching the study of Geometry, branch is Mathematics that presents the smallest index of learning into internal and external evaluation of the students. / Este trabalho apresenta um estudo de Geometria baseada no Triângulo. São abordados alguns aspectos históricos sobre o surgimento da Geometria e a discussão sobre o Quinto Postulado de Euclides. Demonstramos resultados conhecidos e importantes como o Teorema de Pitágoras e a soma dos ângulos internos de um triângulo. Demonstramos ainda alguns resultados considerados como verdades, mesmo que suas demonstrações sejam pouco conhecidas, como “todo triângulo é um polígono convexo”. Por fim, são demonstrados resultados interessantes da Geometria do Triângulo que não são amplamente divulgados entre estudantes e professores, como a reta de Euler, a circunferência dos nove pontos, os Teoremas de Ceva e de Menelaus e a relação de Stwart. Espera-se que este trabalho sirva de fonte de pesquisa para estudantes e professores, e que motive os mesmos a estarem em constante pesquisa e estudo da Geometria, ramo da Matemática que apresenta os menores índices de aprendizagem nas avaliações internas e externas dos estudantes.
