This article presents results of a qualitative research conducted in the first semester of 2014 in a Geometry course, which aimed to answer the question: how students of a professional Masters in Mathematics Teaching, using didactic and technological resources to solve problems involving Taxicab Geometry? From an initial activity of location of points and building knowledge about the taxi’metric, it was proposed situations-problem real and distinct for every student to solve for some time and they meet at a workshop with the whole class. During the realization of this we resumed some solutions and we come to formalize the concepts of midpoint and mediatrix in Taxicab Geometry and its comparison with the same concepts in Euclidean Geometry. The representations of students, on squared paper and the help of GeoGebra in the resolution of the sequence of situations-problem activities, showed that such concepts were purchased and applied to fully satisfactorily.
