3. |
Construct the inscribed circle of heptagon 2. | ||||

4. |
Construct the inscribed heptagon of circle 3, pointing to the right. | ||||

5. |
Construct the inscribed circle of heptagon 4. | ||||

6. |
Construct the circumscribed heptagon of circle 1, pointing to the left. | ||||

7. |
Construct the circumscribed heptagon of (the circumscribed circle of) heptagon 6, pointing to the right. | ||||

8. |
Repeat this three times.Construct the circumscribed heptagon of heptagon 7, pointing to the left. | ||||

9. |
Construct the circumscribed heptagon of heptagon 8, pointing to the right. | ||||

10. |
Construct the circumscribed heptagon of heptagon 9, pointing to the left. | ||||

11. |
Construct the circumscribed circle of heptagon 10. | ||||

12. |
Extend the upper and lower lefthand sides of heptagon 10 to the left, upto the horizontal centerline. | ||||

13. |
Construct a circle centered at the lefthand angular point of heptagon 10, tangent to circle 1 at the lefthand side. | ||||

14. |
Copy circle 13 to the intersection of lines 12, and move this circle (copy and delete original) to its own righthand intersection with the horizontal centerline. | ||||

15. |
Construct a circle centered at the lefthand intersection of circle 1 and the horizontal centerline, tangent to circle 3 at the lefthand side. | ||||

16. |
Construct a circle concentric to circle 15, tangent to circle 5 at the lefthand side. | ||||

17. |
Copy circles 15 and 16 to the righthand intersection of circle 14 and the horizontal centerline. | ||||

18. |
Construct two circles concentric to circle 14, tangent to circles 17 at the lefthand sides. | ||||

19. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the lefthand intersections of circles 3 and 5 with the horizontal centerline. | ||||

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

21. |
Construct a circle concentric to circle 19, tangent to circle 15 at the lefthand side. | ||||

22. |
Copy circles 19, 20, and 21 two times, to the centers of circles 1 and 14. See detail. | ||||

23. |
Construct three pairs of parallel lines, tangent to circles 22 at both sides. See detail. | ||||

24. |
Construct a "two-points" circle between the lefthand intersection of circle 5 and the righthand intersection of the outer righthand circle 22 with the horizontal centerline. | ||||

25. |
Circles 1, 3, 5, 11, 14, 18, and 24, and lines 23, are used for the final reconstruction. | ||||
