ab: 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.
