Example.
A.B.C. is a triangle, whose sides A.C. and B.C, are equall to E.D. and D.F, the two sides of the triangle D.E.F, but bicause the angle in D, is greatter then the angle C. (whiche are the ij. angles contayned betwene the equal lynes)
therfore muste the ground line E.F. nedes bee greatter thenne the grounde line A.B, as you se plainely.
[ The xvi. Theoreme.]
If a triangle haue twoo sides equalle to the two sides of an other triangle, but yet hathe a longer ground line thẽ that other triangle, then is his angle that lieth betwene the equall sides, greater thẽ the like corner in the other triangle.
Example.
This Theoreme is nothing els, but the sentence of the last Theoreme turned backward, and therfore nedeth none other profe nother declaration, then the other example.
