This category contains results about Affine Geometry.Definitions specific to this category can be found in Definitions/Affine Geometry.
Affine geometry is the study of the geometry of affine spaces.
It provides a modern axiomatic approach to the study of configurations of lines, planes and hypersurfaces.
In particular an affine space can be thought of as a finite dimensional vector space with no distinguished origin, and its affine transformations are those that preserve collinearity.
