75. Ὁμοίως δέ, κἂν ἀπὸ τοῦ Γ κέντρου πρὸς ὀρθὰς ἀνασταθῇ εὐθεῖα, ἐπὶ δὲ ταύτης τὸ ὄμμα τεθῇ, καὶ μετακινῆται τὸ ὁρώμενον μέγεθος κατὰ τῆς τοῦ κύκλου περιφερείας παράλληλον ὄν τῇ εὐθείᾳ, ἐφʼ ἧς τὸ ὄμμα, ἴσον ἀεὶ τὸ ὁρώμενον ὀφθήσεται. Ad prop. XL. |76. Λέγω, ὅτι ἡ ΑΒ κτλ. p. 220, τουτέστιν· ὅταν ἡ ∠Ζ τὴν θέσιν ἐν τῷ κύκλῳ ταύτην σχοίη, ἐλάττων ὀφθήσεται ἤπερ, ὅτε ἦν ἀναστᾶσα μὴ πρὸς ὀρθάς.
