Affine geometry is a geometry that removes the concepts of length and angles from Euclidean geometry. It is more general than Euclidean geometry, but more specific than projective geometry. For any oblique coordinate system on a plane, the linear equations x'=ax+by+p, y'=cx+dy+q, [Tachibana Shunichi] ©Shogakukan "> Diagram of affine transformation Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
