14. |
Construct a circle centered at the righthand intersection of circle 5 and the horizontal centerline, tangent to circle 9 at the righthand side. | ||||

15. |
Construct a circle concentric to circle 1, tangent to circle 14 at the righthand side. | ||||

16. |
Copy circle 6 to the righthand intersection of circle 15 and the horizontal centerline. | ||||

17. |
Construct a "two-points" circle between the center of circle 8 and the lefthand intersection of circle 16 and the horizontal centerline. | ||||

18. |
Construct a "two-points" circle between the lefthand intersections of circles 1 and 13 with the horizontal centerline. | ||||

19. |
Copy circle 18 to the center of circle 16. | ||||

20. |
Construct a circle concentric to circle 1, tangent to circle 19 at the righthand side. | ||||

21. |
Copy circle 6 two times, the first to the righthand intersection of circle 20, the second to the lefthand intersection of the first, both with the horizontal centerline. | ||||

22. |
Construct a circle concentric to the first circle 21, tangent to the second at the lefthand side. | ||||

23. |
Copy circle 22 to its lower intersection with circle 20, and move this circle to its own corresponding intersection. | ||||

24. |
Construct a "two-points" circle between the inner intersections of circles 21 with the horizontal centerline, as shown. | ||||

25. |
Copy circle 24 to the center of circle 23. | ||||

26. |
Copy circle 22 to the upper intersection of circle 20 and the vertical centerline. | ||||

27. |
Copy circle 1 to the lower intersection of circle 26 and the vertical centerline. | ||||

28. |
Construct a circle concentric to circle 1, tangent to circle 27 at the upper side. | ||||

29. |
Copy circle 22 to the center of circle 27. | ||||

30. |
Construct a circle centered at the upper intersection of circle 28 and the vertical centerline, tangent to circle 29 at the lower side. | ||||

31. |
Copy circle 6 to the lefthand intersection of circles 28 and 30. | ||||
