Ἐὰν δεδομένα μεγέθη ὁποσαοῦν συντεθῇ, καὶ τὸ ἐξ αὐτῶν συγκείμενον δεδομένον ἔσται. συγκείσθω γὰρ ὁποσαοῦν δεδομένα μεγέθη τὰ ΑΒ, ΒΓ· λέγω, ὅτι καὶ τὸ ἐκ τῶν ΑΒ, ΒΓ συγκείμενον τὸ ΑΓ δεδομένον ἐστίν. ἐπεὶ γὰρ δέδοται τὸ ΑΒ, δυνατόν ἐστιν αὐτῷ ἴσον πορίσασθαι. πεπορίσθω καὶ ἔστω τὸ ΔΕ. πάλιν, ἐπεὶ δέδοται τὸ ΒΓ, δυνατόν ἐστιν αὐτῷ ἴσον πορίσασθαι. πεπορίσθω καὶ ἔστω τὸ ΕΖ. ἐπεὶ οὖν ἴσον ἐστὶ τὸ μὲν ΑΒ τῷ ΔΕ, τὸ δὲ ΒΓ τῷ ΕΖ, ὅλον ἄρα τὸ ΑΓ ὅλῳ τῷ ΔΖ ἐστιν ἴσον· δέδοται ἄρα τὸ ΑΓ· ἴσον γὰρ αὐτῷ πεπόρισται τὸ ΔΖ.
