tyska-engelska översättning av affine geometrie

affine geometryAs an alternative to the axiomatic approach, affine geometry can be studied via the properties of affine transformations, which do not, in general, preserve distances or angles, but do preserve alignment of points and parallelism of linesThe notion of parallelism remains central to affine geometry, in which the parallel postulate is replaced by Playfairs axiom, a version of the postulate that relies on neither distance nor angle size
