CONICORUM LIBER IV. 81 posita E/IZ. dico, EAZ cum EzlH in pluribus punctis non concurrere quam in duobus. nam si fieri potest, in tribus concurrat z/, E, ®y ducaturque sectiones ABj AF contingens AK^ et ducta AE producatur^), prius autem sint et parallelae AK, AE', AE in A in duas partes aequales secetur, ducaturque AA» AA igitur diametrus erit sectionum coniugatarum [II, 34] sectionesque inter A, E m M^ N secat. a ® rectae AE parallela ducatur @ZH\ itaque erit [I def. 4] in altera sectione @S= lElZ, in altera autem &^-==SH quare etiam fiZ = SH-^ quod fieri non potest. AKj AE igitur parallelae ne sint, sed in K concurrant, et reliqua eadem comparentur, productaque AK cum Z@ in P concurrat. eodem igitur modo, quo antea, demonstrabimus, esse [III, 19; Eucl. V, 16] in sectione ZAE A KxKEiAK^ = ZPxP®: PA^, in HAE autem AKxKE: AK^ ==HPxP&: PA\ itaque HPxP® = ZPxP® [Eucl. V, 9]; quod fieri non potest. ergo EAZ cum EAH in pluribus punctis non concurrit quam in duobus. 1) Hoc addidit propter secundam figuram. ApolloniuB ed. Heiberg. II.
