This research presents an investigation into how teachers understand the deduction of the demonstration of a property that relates to the number of diagonals of a prism from a work with digital technology. Our intention is based on the recording of the meetings held with the Mathematics teachers of a state school in Aparecida - SP. The generated recordings were transcribed and the analysis of these results turns to the contribution that the technologies can give during the process of deduction of demonstration of situations of the context of the geometry. In this way, we investigate how GeoGebra favors in the work of visualization and generalization of properties in Geometry, through the exploration and investigation of mathematical elements. We start this work by highlighting some theoretical considerations about demonstrations and the use of digital technologies. It is a qualitative research, developed according to a case study, which uses a phenomenological analysis through two moments: the deographic and Nomothetic analyzes. This analysis allowed us to see how teachers deduce the demonstration of geometric property when working with digital technology
