This work is inserted in the context of teaching-learning Spatial Geometry in Basic Education, in particular, teaching Perspective by High School students and the relations between three-dimensional objects and their representations in the plain. We have used the dynamic geometry environment, CABRI 3D, considering the limitations existing of the paper and pencil environment. The difficulties of students in relation to three-dimensional representations into two-dimensional environment, were researched by Parzysz (1988, 1989, 1991, 2001), and our work was basis in his theoretical Geometry presuppositions. Our aim is verify how the education of the perspective can help students to change or to articulate different points of view of three-dimensional geometric object. Besides, to notice how CABRI 3D can contribute with them, so that they will articulate the real image and its representations. Design Experiments was adopted as the methodology of this work. It was developed by Steffe and Thompson (2000), Doerr and Wood (2000), Cobb et al (2003) and Collins et al (2004). High School students of a private school of the state of São Paulo participated in this work. Their productions showed that the changes between the paper and pencil (static) environment and the dynamic geometry environment CABRI 3D, contributed so that the students mobilize and articulate knowledge between the image and its representations. Finally, we pretend that this work was used as a tool to enlarge the visualization capacity and to sensitize the look of the students for the representations perspective of three-dimensional objects
