108. Ὥστε καὶ τῆς ΕΑ p. 102, 23] ἐπεὶ γὰρ δύο εἴδη τὰ ΕΒ, Β∠ δεδομένα τῷ εἴδει πρὸς ἄλληλα λόγον ἔχει δεδομένον, καὶ αἱ πλευραὶ αὐτῶν πρὸς ἀλλήλας λόγον ἕξουσι δεδομένον. 109. Καί ἐστι τὸ πλάτος τοῦ παραβλήματος p. 104 8–9] τὸ μὲν ἀληθῶς πλάτος τοῦ ΑΓΗΒ παραλληλο- γράμμου ἐστὶν ἡ ΑΘ πρὸς ὀρθὰς οὖσα τῇ ΑΒ· αὐτοῦ δὲ τούτου τοῦ ΑΓΗΒ παραβλήματος ὡς ἐπὶ τούτων τῶν τεσσάρων εὐθειῶν τῶν ΑΒ, ΒΗ, ΗΓ, ΓΑ μήκους ὄντος τοῦ ΑΒ, πλάτος ἔσται τὸ ΑΓ· ἐπὶ γὰρ τῶν προκειμένων τεσσάρων εὐθειῶν τὸ πλάτος ζητεῖ, οὐ τὸ ἀληθῶς τοῦ χωρίου πλάτος· ἄλλη γάρ ἐστι παρὰ τὰς τέσσαρας ὡς ἡ ΑΘ.
