71. Ἡ ΝΟ p. 21Ο, ἡ ΝΟ γὰρ ἐκτὸς πεσεῖται τοῦ ΛΣΜ τμήματος· ἡ γὰρ ΝΞ τῆς ΝΡ μείζων ἐστίν· ἐπὶ γὰρ τῆς ΝΞ ἐστι τὸ κέντρον τοῦ κύκλου τοῦ ΛΣ· μείζων γάρ ἐστι τῆς ΛΝ. ἐπεὶ γὰρ ἐν κύκλῳ τῷ ΛΞΜ εὐθεῖά τις ἡ ΝΞ εὐθεῖάν τινα τὴν ΛΜ δίχα καὶ πρὸς ὀρθὰς τέμνει, ἐπὶ τῆς ΝΞ ἄρα ἐστὶ τὸ κέντρον τοῦ ΛΞΜ κύκλου. ὑπόκειται δὲ ἡ ΝΞ μείζων τῆς ἐκ τοῦ κέντρου, ἐπειδὴ καὶ ἡ ΕΖ, καὶ ἀεὶ ἡ ἔγγιον τοῦ κέντρου τῆς ἀπώτερον μείζων.
