KnowraAffine geometryLinked fromLinked fromThe 17 pages that link to Affine geometry, each with the reason it gives.All 17Broader topic 1Related 7Narrower topic 5Compared with 4Projective geometryCompared with: Affine geometry preserves parallelism, which projective transformations need not preserve.Distance geometryCompared with: Affine transformations can change distances, so affine structure is not the focus here.Complete quadrilateralCompared with: In an affine plane, parallel defining lines lack finite intersections, unlike in projective completion.Projective dualityCompared with: Projective duality relies on projective incidence and does not preserve affine notions such as parallelism.
