A utilização do software GeoGebra como instrumento para compreensão dos conceitos e resultados da geometria plana

Abstract

Mathematics education has been undergoing a process of change that has intensified mainly during the COVID-19 pandemic, as today's society is immersed in what is called Education 5.0. In this type of "education", the approach is more focused on the digital technologies used in the educational process to guarantee a better socio-emotional development for the student. The National Common Curriculum Base (BNCC), through its general competences, learning objectives, in the competences and skills of various curricular components, recommends the use of digital technologies aimed at the students' experiences. It is in this sense that the use of GeoGebra, as a technological resource, can guarantee a better approach to mathematical concepts, as it is a dynamic software and tends to help in understanding the contents. The choice of the approach of using GeoGebra in the area of Geometry is due to its presence in everyday life, but also in various mathematical or physical contents and in various professions. The main objective of this work is to demonstrate Plane Geometry concepts using GeoGebra software for high school students, in addition to analyzing its potentialities and limitations in exploring Plane Geometry concepts and solving questions of the Brazilian Mathematics Olympiad of Public Schools (OBMEP). For this, the methodology used is of a qualitative nature, bibliographic and exploratory. Finally, the results obtained through the demonstrations of the theorems and the solutions of OBMEP questions show that GeoGebra can be used as a methodological resource in the teaching of Mathematics and mainly in the demonstration of Plane Geometry theorems.
