... c−b / d−b is called the cross-ratio of these points. Lemma 4.1’. Projections preserve cross-ratios of points. Definition 4.3. The cross-ratio of four lines lying in one plane and passing through one point is the cross-ratio of the four points at which these lines intersect an arbitrary line l. Remar ...
