Abstract: | A new geometric characterization of the real absolute planes is presented, which is based upon few and simple axioms concerning properties of a congruence relation. The ordering properties are developed from two axioms concerning triangles and circles. We use essential results of reflection geometry in order to prove that the structures under consideration have the well-known representations. |
