A sixth residuall line is when the square of the whole line,* 1.1 exceedeth the square of the line adioyned, by the square of a line incommensurable vnto it in length, and neither the whole line nor the line adioyned is commensu∣rable in length to the rationall line.

As suppose the residuall line to be CD, and the lyne adioyned to

[illustration]

be ••C, and the whole lyne composed of them let be ED, and let the square of the whole lyne ••D exceede the square of the line adioyned by the square of the lyne F, which line F let be incommensurable in length to the whole lyne ED: moreouer let neither the whole lyne CD nor the line adioyned EC, be comm••nsurable in length to the rationall line A••, then shall the residuall lyne CD be by this explica∣tion a sixt residuall lyne, and the last.
