159. Καὶ τοῦ ΒΗ ἄρα p. 148, 22] ἐπεὶ γὰρ τοῦ ΑΒΓ πρὸς τὸ ∠ΕΖ λόγος ἐστὶ δοθείς, ἔστι δὲ καὶ τοῦ ΑΒΓ πρὸς τὸ ΒΗ λόγος δοθείς, καὶ τοῦ ΒΗ ἄρα πρὸς τὸ ΔΕΖ λόγος ἐστὶ δοθείς. πάλιν ἐπεὶ τοῦ ΒΗ πρὸς τὸ ΔΕΖ λόγος ἐστὶ δοθείς, ἔστι δὲ καὶ τοῦ ΕΘ πρὸς τὸ ∠ΕΖ λόγος δοθείς, καὶ τοῦ ΒΗ ἄρα πρὸς τὸ ΕΘ λόγος ἐστὶ δοθείς. 160. Καὶ δῆλον, ὅτι καί, ἐὰν μὴ ἀπὸ τῆς ΕΖ τετράγωνον ἀναγράψωμεν, ἀλλὰ ἀπὸ ἄλλης τινός, οἷον τῆς ΖΞ, καὶ πρὸς ἐκείνην, οἷον τὴν ΖΞ, λόγον ἔχει δεδομένον ἡ ΒΓ.
