If the three straight lines joining the corresponding vertices of two triangles ABC and DEF all meet in a point G (the perspector), then the three intersections of pairs of corresponding sides lie on a straight line PQR (the perspectrix).


The 10 lines and 10 points of intersection of three lines at a time form what is called the Desargues configuration.
