Here take OA, OB, each = 2; upon AB describe squareACDB; bisect BD in E, and draw EM parallel to CD;describe semicircle and find points F, G, as already shown.Make BK = BD, BH = BE and KL = DE; join L MP,K MP, etc.; also A C.Y., G C.Y., etc.; and on eight pointsthus formed describe circle required.… … Here take A 5 to right of O; erect the perpendicular AB.2 = radius of given circle; join B C.Y. and A C.Y.; take 02 to left of A; join 0 MP, cutting A C.Y. in D. Draw DEparallel to AB; then with centre E and distance ED describecircle required. For AD = AC = BE; then E is 2 withinP.P. and 5 to…
