THE XXXIIII. CONCLVSION. To make a square quadrate aboute annye circle assigned.

Drawe two diameters in crosse waies, so that they make foure righte angles in the centre. Then with your compasse take the length of the halfe diameter, and set one foote of the compas in eche end of those diameters, drawing twoo arche lines at euery pitchinge of the compas, so shall you haue viij. arche lines. Then yf you marke the prickes wherin those arch lines do crosse, and draw betwene those iiij. prickes iiij right lines, then haue you made the square quadrate accordinge to the request of the conclusion.

Example.

A.B.C. is the circle assigned

[illustration] diagram

in which first I draw two diameters, in crosse waies, making iiij. righte angles, and those ij. diameters are A.C. and B.D. Then sette I my compasse (whiche is o∣pened according to the se∣midiameter of the said cir∣cle) fixing one foote in the end of euery semidiameter, and drawe with the other foote twoo arche lines, one on euery side. As firste, when I sette the one foote in A,

then with the other foote I doo make twoo arche lines, one in E, and an other in F. Then sette I the one foote of the com∣passe in B, and drawe twoo arche lines F. and G. Like wise settinge the compasse foote in C, I drawe twoo other arche lines, G. and H, and on D. I make twoo other, H. and E. Then frome the crossinges of those eighte arche lines I drawe iiij. straighte lynes, that is to saye, E.F, and F. G. also G.H, and H.E, whiche iiij. straight lines do make the square quadrate that I should draw about the circle assigned.
