To make a square quadrate in a circle assigned.
Draw .ij. diameters in the circle, so that they runne a crosse,
and that they make .iiij. right angles. Then drawe .iiij. lines,
that may ioyne the .iiij. ends of those diameters, one to an
other, and then haue you made a square quadrate in the circle
appointed.
_Example._
[Illustration]
A.B.C.D. is the circle assigned, and A.C. and B.D. are the two
diameters which crosse in the centre E, and make .iiij. right
corners. Then do I make fowre other lines, that is A.B, B.C,
C.D, and D.A, which do ioyne together the fowre endes of the ij.
diameters. And so is the square quadrate made in the circle
assigned, as the conclusion willeth.
