The role of geometry in secondary school is changing due to the spread of computer animation in everyday life. For that reason, the author suggests dealing with the concept of perspectivity and space perception in mathematics lessons in grade 9 in a way that the number of lessons per week does not increase. His starting points are central similarity and reflection in the Euclidean plane. After defining central and axial perspectivity of a triangle he formulates Desargues' theorem and presents some tasks as application of the theorem.
