w an other
gemowe line, whiche shall be parallele to two sides of the
likeiamme. Afterward shall you draw .ij. lines more for the
accomplishement of your worke, which better shall be perceaued
by a shorte exaumple, then by a greate numbre of wordes, only
without example, therefore I wyl by example sette forth the
whole worke.
_Example._
[Illustration]
Fyrst, according to the last conclusion, I make the likeiamme
E.F.C.G, equal to the triangle D, in the appoynted angle whiche
is E. Then take I the lengthe of the assigned line (which is
A.B,) and with my compas I sette forthe the same length in the
ij. gemow lines N.F. and H.G, setting one foot in E, and the
other in N, and againe settyng one foote in C, and the other
in H. Afterward I draw a line from N. to H, whiche is a gemow
lyne, to ij. sydes of the likeiamme. thenne drawe I a line also
from N. vnto C. and extend it vntyll it crosse the lines, E.L.
and F.G, which both must be drawen forth longer then the sides
of the likeiamme. and where that lyne doeth crosse F.G, there I
sette M. Nowe to make an ende, I make an other gemowe line,
whiche is parallel to N.F. and H.G, and that gemowe line doth
passe by the pricke M, and then haue I done. Now say I that
H.C.K.L, is a likeiamme equall to the triangle appointed, whiche
was D, and is made of a line assigned that is A.B, for H.C, is
equall vnto A.B, and so is K.L. The profe of y^e equalnes of
this likeiam vnto the triangle, dependeth of the thirty and two
Theoreme: as in the boke of Theoremes doth appear, where it is
declared, that in al likeiammes, when there are more then one
made about one bias line, the filsquares of euery of them muste
needes be equall.
THE XVII. CONCLVSION.
To make a likeiamme equal to any right lined figure, and
that on an angle appointed.
The readiest waye to worke this conclusion, is to tourn that
rightlined figure into triangles, and then for euery triangle
together an equal likeiamme, according vnto the eleuen
conclusion, and then to ioine al those likeiammes into one, if
their sides happen to be equal, which thing is euer certain,
when al the triangles happen iustly betwene one pair of gemow
lines. but and if they will not frame so, then after that you
haue for the firste triangle made his likeiamme, you shall take
the length of one of his sides, and set that as a line assigned,
on whiche you shal make the other likeiams, according to the
twelft conclusion, and so sha
