Benefícios do programa geogebra para o ensino de geometria

Abstract

This work suggest a new alternative to teach geometry, resorting to the software Geogebra. Some apps had been created for the student interact and deduce the formulas or properties. The assignments were chosen for help the student to don’t memorize formulas but deduce them (mainly refers area, even has an app about sum of external angles), which become easy to comprehension about others subject, inclusive about areas, because the student wins the deduction to himself. In order to this, I will introduce abstracts and pictures from the assignments suggested. The Geogebra is a dynamic and free software, available multiple language, inclusive Portuguese, providing tools to teach-learning geometry, calculus, algebra, and statistics, among other. This work has reports from students about the assignments, with opinions, suggestions and an abstract to each app, as were applied and were built, and with some program features. Still the apps are not the real proof, this work objective the possibility to the student create a deductive-logical capacity. There is a chapter for all statements for the work results. Thus, I conclude an analysis about new technologies with their different approaches and the advantages to use this tool to teach middle and high school.
