A geometria dinâmica no estudo e classificação dos triângulos: adaptando exercícios do livro didático e construindo atividades com o GeoGebra

Abstract

In this work we aim to investigate the possibilities and contributions of Dynamic Geometry of Geogebra software for the Study of Triangles in elementary school when compared to conventional approaches presented in textbooks. This is an exploratory research and also un research participant developed in a State school of elementary and high school in the city of Guarabira with a group of 8th year and their teacher regent. To achieve this goal first conducted a bibliographic study on the dynamic geometry and the study of triangles, then select textbook exercises used by the reference school and adapt these exercises to be applied to the Geogebra software and finally perform a didactic intervention in school where we develop the adapted activity and analyze together with the teacher the viability of the proposal. Given the survey, noted that the math teacher and the students did not know the dynamic geometry software GeoGebra, but familiarized themselves easily with the application. The review of literature confirmed about the possibilities and contributions of Dynamic Geometry for the study of geometry and the activities proposed in class was perceived motivation of the students in the study of triangles. From the movements made in the triangles in Geogebra they managed to make their own analysis of the issues addressed and about. The teacher, despite of following the approaches the textbook realized the contribution of software for teaching and learning the study of triangles and theirs properties.
