A utilização do GeoGebra como auxílio didático no ensino dos polígonos inscritíveis e circunscritíveis

Abstract

The use of technological resources has helped to significantly improve the teaching and learning process of geometry. This work presents an approach of the inscribable and circumscribable polygons in particular, the quadrilaterals and triangles, as well as suggestions of activities involving these contents.We present a teaching-learning method of dynamic geometry using GeoGebra, showing the available resources to create an interactive environment that can be used as a didactic aid, thus generating a dynamism in the contents worked in the classroom. The methodology suggested in the activities consists in presenting a step-by-step of the constructions of the elements, namely polygons, notable points and circles associated with the polygons, so that it is possible, through manipulation and investigation of the elements of the figures, exploring the dynamic aspect of GeoGebra, to cause the student deduce the main properties that involve the inscribable and circumscribable polygons.
