Uso de materiais concretos e de práticas no desenvolvimento de trigonometria no ensino médio

Abstract

In order to verify if the use of concrete and practical materials can help in the teaching learning process of Trigonometry in high school, a study of an applied nature was carried out in the 2nd year C class of the Secondary School in the School Unit Edith Nobre de Castro, in the city of São Raimundo Nonato. The approach of this research is qualitative and quantitative. The objective was to construct a Simple Theodolite, capable of measuring angles both vertically and horizontally and the presentation of trigonometry content using concrete materials and adopted practices. With the data obtained at the end of the research it was possible to conclude that the use of concrete materials can aid in the teaching of Trigonometry in the Rectangle Triangle, leading
