This work is focused on the application os spatial geometry teaching techniques especially the teaching of polyhedrons, being detached the Euler's theorem and regular polyhedrons (Plato's polyhedrons).Initially we analyzed the definitions and theorems and their respective demonstrations, including some history of the fantastic mathematical Leonhardo Euler, and his curiosities about his theorem for polyhedrons. We also discussed the educational difficulties of mathematics teaching and the elements that can be linked to these difficulties as well as alternatives that may be applied to teachers' teaching practice in this area. With so many difficulties, we proposed a teaching methodology based on a combination of two techniques: use of software and cooperative learning, for both methods have been much discussed as a viable alternative to education. We also detached the main thought strands of the use of software as a teaching tool or teaching machine, as well as we analyzed the cooperative teaching characteristics, showing the difficulties encountered when we tried to implement this teaching method, in addition, we also put in relief the advantages achieved after overcoming the initial obstacles. It was also analyzed the softwares Poly and Educandus that have been used in the different educational project, where we detached their potential beyond their limitations, suggesting alternatives for due complementation of the teacher who accompanied the students involved in the study. We also suggested, activities directed for the use of Poly in order to lead the participant to explore the software's potential to its maximum in order to minimize the visualization difficulties and representation of polyhedrons. Finally, we applied qualitative and quantitative assessments where we verified the potential of the used methodology compared to formal education, and we did an analysis of the most common mistakes
