A relevância da fórmula de heron para a formação dos alunos do 9º ano do ensino fundamental da escola pública

Abstract

Mathematics as every area of human knowledge undergoes changes during the sociocultural advancement of each people, although the formulas or the content do not undergo many changes, the method that is passed on modifies with the objective of increasingly facilitating both the review of this data content, as to improve the process of acquisition of this by students. In this perspective, the Heron formula is indispensable, mainly as didactic content of the mathematics discipline in both Elementary and High School, being used as a resource to calculate the area of a triangle using only the measures of the sides, that is, this formula that does not need the height of the mentioned polygon, which is indispensable in other expressions in the calculation of the area of triangles. In this article, we will discuss the relevance of Heron's Formula to the formation of 9th grade students, how this can contribute to the teaching / learning process of mathematics. Also, we discuss a little of the historical evolution of geometry, the teaching of mathematics in schools and we describe Heron's Formula, its historical aspects. The method of investigation of this article is bibliographic of a qualitative nature, because in order to arrive at the findings established here, it was of immeasurable importance to know and to lecture under the theoretical aspects.
