of pencil 1, 22 of pencil 2. 0, theintersection of 51 and 32, is the vertex of a pencil of which11 and 22 are transversals. Hence the pencils 1 and 2 arcprojective, and corresponding rays are rays to the points ofintersection of the rays of pencil 0 with 11 and 22.

Hencecorresponding points of the projective ranges 11 and 22 arelocated by the intersection with 11 and 22 of lines connecting(11) and (22) respectively with any point of 00. The…
