καὶ πεπερασμένην εὐθεῖαν κατὰ τὸ συνεχὲς ἐπ᾽ εὐθείας ἐκβαλεῖν.
To produce a finite straight line continuously in a straight line.

I translate πεπερασμένην by finite, because that is the received equivalent, and because any alternative word such as limited, terminated, if applied to a straight line, would equally fail to express what modern Italian geometers aptly call a rectilineal segment, that is, a straight line having two extremities.
