The objective of this work is to present a didactic proposal that explores the resolution of two issues of the Brazilian Public Schools Mathematics Olympiad, from the development of visualization skills and geometric reasoning supported by GeoGebra software. As a methodology for its development, Didactic Engineering was adopted in its first two phases - preliminary analysis and a priori analysis - in which the epistemological and didactic obstacles in the teaching of Geometry were raised, as well as a didactic proposal was presented with the modeling of two problems extracted from the referred Olympiad, dealing with the subject of planning of geometric solids, with the GeoGebra software. Finally, it is expected that this work can be a guide for the mathematics teacher, with regard to his work in the field of Geometry using this software, as well as a possibility for the student to develop geometric thinking from the visualization, in mathematical problems that do not require manual calculations, but only the perception of geometry.
