| Abstract: | In an affine plane oriented distance d and oriented angle w (between non-oriented lines) are introduced as mapping into  , fulfilling certain axioms. Examples show, that the use of w is of advantage in elementary geometry. Axiomatic consequences of generalizing d, w to mappings into ordered abelian groups are considered.Herrn Helmut Salzmann zum 60. Geburtstag |
