Introdução à geometria euclidiana axiomática com o geogebra

Abstract

Knowing the great hardship high school students of Minas Gerais public school system have concerning the basic concepts, demonstrations and deductions of the Euclidean Geometry, a small study guide of the axioms that rule these contents was made, and also an introduction to the basic geometry constructions using the Euclidean instruments and the free software GeoGebra. The work’s development brought as a goal to endow the middle school students, attending the eight year (the old seventh grade), a gradual and intuitive understanding of the Euclidian Geometry, trying to fix the basic conceptual aspects that are deeply necessary for further studies. The proposed activities on chapter four intend to give the student, going trough the concepts shown on chapter two, the opportunity to abstract on a descriptive way and/or use algebraic resources in a process of demonstration of many geometrical forms.
