Abstract
Euclidean planes are characterized as affine planes with a congruence relation on the set of the pairs of points. Furthermore we study the consequences of the congruence axioms for other incidence structures e.g. finite or half ordered ones, and discuss the question when the 3-reflection theorem is valid.
