Ela se remete a estudos dentro do Mestrado Profissional em Educação Matemática da Universidade Federal de Juiz de Fora. Damos tratamento teórico e operacional aos temas mais básicos da Geometria Projetiva a partir dos teoremas de Menelau e Ceva, cujos pressupostos estão enraizados nos conceitos de colinearidade e concorrência. Sugere-se uma reflexão a partir do que se percebe no ensino de Geometria no Brasil, principalmente em torno do estudo de triângulos e do que a eles se agregam. Faz-se um resgate histórico dos teoremas mencionados e propõem-se algumas atividades norteadoras, de modo a levar o aluno (sujeito) a se defrontar com novas possibilidades de resolução de problemas. Apresenta-se um início de proposta de tratamento metodológico sobre dados de pesquisa de campo projetada. / This work is part of a research about Projective Geometry as pedagogic tool in High School. The research itself is part of studies developed during the Professional Master Degree in Mathematics and Education at Federal University of Juiz de Fora. We try to give a theoretical and operational approach to basic themes of Projective Geometry from the theorems of Menelau and Ceva, which assumptions are rooted in the concepts of collinearity and concurrency. It is suggested, then, a mature reflection of what we perceive in the teaching of Geometry in Brazil, mainly about the study of triangles and its relations. A historical survey of the theorems mentioned above is made and we propose some activities to take the student (subject) to face new possibilities to solve problems. It is presented the start of a proposal of methodological approach to data of a projective field research.
