CONSTRUCTION II.
Now by the Angle of the Figure, to de∣lineate any regular Poligon, Let it be required to protract a Hexagon, whose side as afore is 100 parts; first I draw a line and make it 100 of those parts, then I sind in the precedent Table the Angle of a Hexagon at the figure to be 120 degrees: Then on each side of the drawn line, I lay down an Angle of 120 deg. (according to the 5 precedent propositions) and so work 6 times, (or as many times as your Poligon hath sides) making each side 100 parts,* 1.1 and each Angle 120 degrees; so shall you have enclosed the Poligon PPPPPP, as required.
