El concepto del triángulo para calcular áreas geométricas

Abstract

Abstract: Since ancient times, geometry has been considered a fundamental pillar in mathematics, since it has contributed to the development of the teaching - learning of calculus of different geometric figures. For this reason, the present study aims use innovative strategies that improve understanding of the concept of triangle for the calculation of geometric figures in third year students High School from the Daniel Córdova Toral School. In this sense, the research is of type descriptive with a qualitative, quantitative mixed approach, the instrument was used as questionnaire with a Likert scale and the interview as a technique for the teacher of the subject of geometry, in order to collect valuable information to meet the objectives. It was possible to determine the main difficulties presented in learning the calculation of areas of the triangle, evidencing limitations in the understanding of the concept of the triangle and calculation of geometric figures. Finally, suggestions were made that help enhance the abilities of the learners, in such a way that they are motivated to understand and apply the concept of the triangle to the calculation of areas.
