escribe arcs E, E; andwith centre F (right) and same distance describe arcs E, E.Then with centre F (left) and distance equal to that from 1to A, describe arcs cutting the former, so also describe arcsfrom centre F (right). Thus for each point between O and F,we get four points. Having thus found a… … Let the concentric circles EF and AB be drawn; drawdiameters AB and CD at right angles to each other, divideeach quadrant into the same number of equal parts, and joinopposite points; draw perpendiculars from the outer pointsand horizontals from the inner points to meet them; thusdraw perpendicular…
