O uso do Software GeoGebra para o ensino de pontos notáveis no Triângulo

Abstract

In this work, we present an investigation through a didactic sequence, carried out with high school students from a state school located in the municipality of Serra, in the state of Espírito Santo. In our research we approached the Notable Points of a Triangle with the help of Geogebra software, articulating mathematical concepts with dynamic geometry. The results evidenced the need to recall mathematical concepts studied in elementary school years, the importance of the geometric visualization stage in the construction process of the approached concepts and the need to systematize the visual presentation for a better understanding of the concepts.
