a _poynt or prycke_, that small printe of penne, pencyle, or
other instrumente, whiche is not moued, nor drawen from his
fyrst touche, and therfore hath no notable length nor bredthe:
as this example doeth declare.

[Illustration: {"therefore" symbol}]

Where I haue set .iij. prickes, eche of them hauyng both length
and bredth, thogh it be but smal, and thefore not notable.

Nowe of a great numbre of these prickes, is made a _Lyne_, as
you may perceiue by this forme ensuyng. ........................
where as I haue set a numbre of prickes, so if you with your pen
will set in more other prickes betweene euerye two of these,
[Sidenote: A lyne.] then wil it be a lyne, as here you may see
-------- and this _lyne_, is called of Geometricians, _Lengthe
withoute breadth_.

But as they in theyr theorikes (which ar only mind workes) do
precisely vnderstand these definitions, so it shal be sufficient
for those men, whiche seke the vse of the same thinges, as sense
may duely iudge them, and applye to handy workes if they
vnderstand them so to be true, that outwarde sense canne fynde
none erroure therein.

Of lynes there bee two principall kyndes. The one is called a
right or straight lyne, and the other a croked lyne.

[Sidenote: A streghte lyne.] _A Straight lyne_, is the shortest
that maye be drawenne between two prickes.

[Sidenote: A crokyd lyne.] And all other lines, that go not
right forth from prick to prick, but boweth any waye, such are
called _Croked lynes_ as in these examples folowyng ye may se,
where I haue set but one forme of a straight lyne, for more
formes there be not, but of crooked lynes there bee innumerable
diuersities, whereof for examples sum I haue sette here.

So now you must vnderstand, that _euery lyne is drawen betwene
twoo prickes_, wherof the one is at the beginning, and the other
at the ende.

Therefore when soeuer you do see any formes of lynes to touche
at one notable pricke, as in this example, then shall you not
call it one croked lyne, but rather twoo lynes: [Sidenote: an
Angle.] in as muche as there is a notable and sensible angle by
.A. whiche euermore is made by the meetyng of two seuerall
lynes. And likewayes shall you iudge of this figure, whiche is
made of two lines, and not of one onely.

So that whan so euer any suche meety
