English: I modified the File File:Desargues theorem alt.svg a little. Exchanged english by point/line-names and renamed the points with lower-case-letter names to fit into the article de:Projektive Perspektivität. Noted this on the disc-page of user:Jujutacular.
Picture shows the configuration of Desargues's theorem (if it HOLDS). The center of perspectivity is Z, the axis a. The colored triangles are in perspectivity as well from the center Z as from the axis a.
Deutsch: Das Bild zeigt eine desarguessche Konfiguration für den Fall, dass der de:Satz von Desargueserfüllt ist. Die Dreiecke ABC und A'B'C' sind einander perspektiv zugeordnet: Sie liegen zentral-perspektiv zueinander in Bezug auf das Zentrum Z und falls der Satz von Desargues für die Konfiguration gilt, axial-perspektiv zueinander in Bezug auf die Achse a.
