Ἐῶ λέγειν ὅτι καὶ ἄλλῃ τινὶ τεχνολογίᾳ μάχεται ἡ τοιαύτη τῶν γωνιῶν νόησις. διαιρούμενοι γάρ φασι τῆς γωνίας τὴν μέν τινα εἶναι ὀρθὴν τὴν δὲ ἀμβλεῖαν τὴν δὲ ὀξεῖαν, καὶ τῆς μὲν ἀμβλείας ἄλλην καὶ ἄλλην μᾶλλον ἀμβλυτέραν εἶναι, ὡσαύτως δὲ καὶ τῆς ὀξείας.

I pass over the fact that this conception of angles also conflicts with another part of their technical doctrine. For in making divisions they say that one angle is right, another obtuse, and another acute, and that among obtuse angles one is more obtuse than another, and likewise among acute angles.

Je laisse de côté que cette conception des angles contredit aussi une autre partie de leur doctrine. En les divisant, ils disent en effet qu’un angle est droit, un autre obtus, un autre aigu; et que, parmi les angles obtus, l’un est plus obtus qu’un autre, de même aussi parmi les angles aigus.
