Our aim is to determine whether their images are intrinsically governed by the concept, and to do so we have analyzed written records, audio and video recordings and the software construction protocol files. We present an analysis of the tasks performed by prospective mathematics teachers during the resolution of the problem. This environment enables us to obtain a multiplicity of cases with a single construction provided geometric properties are used. To address the notion of regular polyhedron, we elaborated a problematic situation mediated by GeoGebra, due to the advantages that this dynamic environment provides when working with three-dimensional figures. We demonstrate it through the design of situations that allow exploration, formulation and validation of conjectures. Numerous regulatory documents express a revaluation of Geometry, not only when working with manipulative materials but also when dynamic geometric software mediates the work.
