41 Διὰ δὴ τῶν εἰρημένων φανερὸν ὡς δυνατόν ἐστιν γωνίας δοθείσης ὡς τῆς ὑπὸ ΗΑΒ καὶ σημείου ἐκτὸς αὐτῆς τοῦ Γ διάγειν τὴν ΓΗ καὶ ποιεῖν τὴν ΚΗ μεταξὺ τῆς γραμμῆς καὶ τῆς ΑΒ ἴσην τῇ δοθείσῃ. Ἤχθω κάθετος ἀπὸ τοῦ Γ σημείου ἐπὶ τὴν ΑΒ ἡ ΓΘ καὶ ἐκβεβλήσθω, καὶ τῇ δοθείσῃ ἴση ἔστω ἡ ∠Θ, καὶ πόλῳ μὲν τῷ Γ, διαστήματι δέ τῷ δοθέντι, τουτέστιν τῇ ∠Θ, κανόνι δὲ τῷ ΑΒ γεγράφθω κοχλοειδὴς γραμμὴ πρώτη ἡ Ε∠Η συμβάλλει ἄρα τῇ ΑΗ διὰ τὸ προλεχθέν. συμβαλλέτω κατὰ τὸ Η, καὶ ἐπεζεύχθω ἡ ΓΗ· ἴση ἄρα καὶ ἡ ΚΗ τῇ δοθείσῃ.
