However, so that this occurs satisfactorily, she is necessary that the professors, in the paper of facilitadores and mediators of the learning, find a form qualitative teoriaem to transform it practical. In this perspective, Saucers (2000) and Bridge (2003) they stand out that the professors need to have the conscience of that the acquisition of the geometric concepts must occur by means of the accomplishment of activities that involve the pupils in the comment and the comparison of the geometric figures, especially those related with the angular concepts. Finishing, the results of the accomplishment of this project of pedagogical intervention indicate that many difficulties with regard to the education of geometry exist, mainly, with the study of angles. In this direction, the necessity exists of that new strategies of education are used in classroom for the education of this content are not relegated to as a plain one and can take care of the pertaining to school necessities of our pupils.
