101 Ὅτι δὲ ἴση ἐστιν ἡ Ξ∠ τῇ ∠Ζ δῆλον. ἐπεὶ γὰρ παρέλληλός ἐστιε ἡ ΛΞ τῇ ΖΗ, ἰσογώνιόν ἐστι τὸ ΛΞ∠ τρίγωνον τῷ Ζ∠Η. καὶ ἐπεὶ δύο τρίγωνά ἐστιν τὰ ΛΞ∠ Ζ∠Η τὰς δύο γωνίας τὰς ὑπὸ Ξ∠Λ ∠ΛΞ ταῖς ὑπὸ Ζ∠Η ∠ΗΖ δυσὶν ἴσας ἔχοντα καὶ μίαν πλευρὰν τὴν Λ∠ μιᾷ πλευρᾷ τῇ ∠Η ἴσην, καὶ αἱ λοιπαὶ ἄρα πλευραὶ ταῖς λοιπαῖς ἴσαι ἔσονται ἑκατέρα ἑκατέρᾳ τῶν ὑποτεινουσῶν τὰς ἴσας γωνίας. ἴση ἄρα ἡ ∠Ξ τῇ ∠Ζ.
