Draw a circle with radius OA and inscribe hexagon of side OA=1. Draw a
veertical diamter AB. Mark each apex of hexagon with 1to 6. and draw in the
diagonals 1-4, 2-5, 3-6. With the midpoint C as centre and radius CA, draw arc
to intersect radius 0-2 at point 11. Line CA=5/2 and will divide radius 0-2
into the proportion 1/f and 1/f². Draw circle with radius O-11 and at the places
where this circle interesects the radii of the hexagon mark a point and
designate with a number 7 to 12. |
