Pithagoras Theorem by Dynamics Geometry Software

Abstract

This study is about the geometric and algebraic proofs of the Pythagorean Theorem using dynamic geometry software, concerned to secondary school levels. In it is presented a proofs categorization very useful as a tool for teachers, especially when they are looking for teaching resources. Thus, the research provides a set of dynamic constructions designed using GeoGebra and those steps followed in order to build them, which are a good support for both teachers and students
