Projective geometry can be modeled by the affine plane (or affine space) plus a line (hyperplane) "at infinity" and then treating that line (or hyperplane) as "ordinary". Our intuition suggests that we introduce the concept of “translated” subspace. In traditional geometry, affine geometry is considered to be a study between Euclidean geometry and projective geometry.
