Geometria pura elementare, per S. Pincherle.

La linea rella. 35 a) Siano eguali gli angoli alterni-interni AEF, EFD: se allora le rette AB, CD s'incontrassero in 0, nel triangolo EOF langolo esterno AEF dovrebbe essere maggciore dell'interno EFD (1) contro alla supposta eguaglianza di questi angoli: dunque AB,CD non si possono incontrare, cio6 (2) sono parallele. b) Siano eguali gli angoli corrispondenti AEF, CFN: essendo CFN= EFD come opposti al verlice, risultano eguali gli angoli alterni-interni AEF, EFD e si torna al caso a). M A / BFig. G6. c) Siano supplementari gli angoli interni della stessa banda, AEF, EFC: essendo (3) EFD ed (1) ~ IV, teor. 1. (2) Introd. def. 13. (3) ~ I, teor. 3.
