Abstract

Since geometry contains basic tools for students’ mathematical work, it is of indisputable importance to get students to appropriate the basic concepts of this branch of Mathematics, and to also integrate these concepts into geometry as a whole. Geometry contributes to the development of visualization, critical thinking, problem solving, hypothesis management, logical argumentation, and students’ skills in demonstration; it also provides powerful tools to represent and solve problems in all areas of Mathematics, other school disciplines, and real-life problems. The theoretical foundation of this work rests on the use of mathematical language as a means of representing mathematical objects, the transformations of semiotic registers, and the conception of Mathematics as a means and object. This research was carried out through case studies, using action research methods. With the aim of arriving at a set of didactic-methodological guidelines to support teachers in teaching the subject.
