Demonstrações visuais: provas com e sem palavras

Abstract

In this dissertation we will cover demonstrations of several theorems studied in basic education. Such theorems have traditional demonstrations, present in textbooks, very abstract and difficult to understand by students. I decided to bring in this dissertation alternative and more palpable visual demonstrations in order to help teachers justify these results in the classroom class. We will go through various branches of mathematics: Euclidean Geometry, Trigonometry, Identities and Inequalities.
