¶ A Corollary out of Flussates.* 1.1

By this Proposition we may deuide any right line geuen, accordyng to the pro∣portion

Page [unnumbered]

of any right lynes geuen. For let those right lynes hauyng proportion be ioyned together directly, that they may make all one right lyne, and then ioyne them to the lyne geuen anglewise. And so proceede as in the proposition, where you see that the right line geuen AB is deuided into the right lynes AF, FG and GB which haue the selfe same proportion that the right lines AD, DE, and EC haue.

By this and the former proposition also may a right line geuen be easily deui∣ded into what partes so euer you will name.* 1.2 As if you will deuide the line AB in∣to three equall partes, let the lyne DE be made equall to the lyne AD, and the lyne EC made equall to the same by the third of the first. And then vsing the selfe same maner of construction that was before: the lyne AB shall be deuided into three equall partes. And so of any kynde of partes whatsoeuer.
