This paper presents Desargues’ theorem in two ways: – the solution by incidence and succession; - the solution by the application of the descriptive geometry rules. In both cases is possible to show that the points P, Q, R (they are presented in the “Theoretical considerations”) are located on the line of intersection of the plane (ABC) and the plane (EFG), therefore they are collinear.
