A metodologia da resolução de problemas aplicada ao ensino das relações trigonométricas no triângulo retângulo

Abstract

The following text discusses problem-solving as a teaching-learning methodology and its use in teaching trigonometric relationships in the right triangle. With the aim of demonstrating the usefulness of this methodology as an effective pedagogical proposal in teaching the aforementioned mathematical content, we start with the following question: How can the problem-solving methodology be applied to favor the teaching-learning of trigonometric relationships in the right triangle? To answer this question, we organized the work as follows: in the first chapter, we present the problem-solving methodology; in the second, we address a brief history of trigonometry; in the third, we present trigonometry in the right triangle; in the fourth and final chapter, we present a proposal for an activity to be developed in the classroom using the problem-solving methodology in teaching trigonometric ratios in the right triangle and conclude by exposing the results of applying this work in a school of Minas Gerais state network.
