Reconstruction of theCheesefoot Head 17-06-2017 formation | |||||

1. |
Draw a circle. Draw and extend the horizontal and vertical centerlines. | ||||

2. |
Construct the inscribed regular 18-sided polygon of circle 1, pointing to the right. Number the angular points clockwise 1 - 18, starting at the top. | ||||

3. |
Draw the connecting line between angular point (of polygon 2) nr. 13 and the upper intersection of circle 1 and the vertical centerline. | ||||

4. |
Construct a circle concentric to circle 1, tangent to line 3. | ||||

5. |
Draw the connecting line between angular point nr. 12 and the upper intersection of circle 1 and the vertical centerline. | ||||

6. |
Construct a circle concentric to circle 1, tangent to line 5. | ||||

7. |
Draw two rays of polygon 2, from the center of circle 1 to angular points nrs. 1 and 18. | ||||

8. |
Draw the connecting line between angular points nrs. 4 and 14. | ||||

9. |
Construct a circle centered at the intersection of line 8 and the vertical centerline, passing through the intersections of rays 7 and circle 6. | ||||

10. |
Construct a circle centered at the upper intersection of circle 1 and the vertical centerline, tangent to the upper side of polygon 2. | ||||

11. |
Construct a circle concentric to circle 1, tangent to circle 10 at the upper side. | ||||

12. |
Copy circle 10 to the center of circle 1, and move this circle (copy and delete original) to its own lefthand intersection with the horizontal centerline. See detail. | ||||

13. |
Construct a circle concentric to circle 1, tangent to circle 12 at the lefthand side. | ||||

14. |
Copy circle 10 to angular point nr. 18. | ||||

15. |
Construct a line tangent to circle 13 at the lefthand, and to circle 14 at the righthand side. | ||||

16. |
Repeat step (14 and) 15 seventeen times, with respect to the other angular points of polygon 2, as shown. | ||||

17. |
Repeat step 3 seventeen times, with respect to the other angular points of polygon 2, as shown. | ||||

18. |
Construct a circle centered at the upper intersection of circle 13 and the vertical centerline, passing through the intersections of circle 13 and rays 7. | ||||

19. |
Copy circle 18 two times, to the intersections of line 15 with circle 6, and with the upper side of polygon 2. See detail. | ||||

20. |
Construct a line parallel to line 15, tangent to circles 19 at the lefthand sides. | ||||

21. |
Repeat step (19 and) 20 seventeen times, with respect to the other angular points of polygon 2, as shown. | ||||

22. |
Circles 4, 6, 9, and 11, and lines 3, 15, 16, 17, 20, and 21, are used for the final reconstruction. | ||||
