|
|
4. |
| Copy circle 3 seven times, to the other angular points of octagon 2.
|
|
5. |
| Construct a circle, passing through the center of circle 1, tangent to circle 3 and the lefthand circle 4, both at the upper near sides.
|
|
6. |
| Copy circle 5 to the center of circle 1.
|
|
7. |
| Construct a circle centered at the top of octagon 2, tangent to circle 5 at the upper side.
|
|
8. |
| Copy circle 7 to the center of circle 1.
|
|
9. |
| Construct the "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and the upper intersection of the lower lefthand and righthand circles 4.
|
|
10. |
| Copy circle 9 to the center of circle 1.
|
|
11. |
| Construct the "two-points" circle between the center of circle 1, and the upper intersection of the lower and lower righthand circles 4.
|
|
12. |
| Copy circle 11 to the center of circle 1.
|
|
13. |
| Construct a circle centered at the upper intersection of the lower lefthand and righthand circles 4, tangent to circle 5 at the upper side.
|
|
14. |
| Copy circle 13 to the center of circle 1.
|
|
15. |
| Construct the "two-points" circle between the center of circle 1 and the upper intersection of circle 8 and the vertical centerline.
|
|
16. |
| Copy circle 15 to the center of circle 1.
|
|
17. |
| Construct a circle centered at the upper intersection of circle 16 and the vertical centerline, tangent to circle 14 at the upper side.
|
|
18. |
| Copy circle 17 to the top of octagon 2.
|
|
19. |
| Construct a circle concentric to circle 1, tangent to circle 18 at the upper side.
|
|
20. |
| Construct the inscribed regular 58-sided polygon of circle 6, pointing up.
|
|
21. |
| Draw the fifty-eight rays of circle 6, to the angular points of polygon 20.
|
|
22. |
| Remove all parts from circles 6 and 8, and lines 21, such that the shown pattern remains.
|
|
|
|
23. |
| Construct the inscribed regular 42-sided polygon of circle 10, pointing up.
|
|
24. |
| Draw the forty-two rays of circle 10, to the angular points of polygon 23.
|
|
25. |
| Remove all parts from circles 10 and 12, and lines 24, such that the shown pattern remains.
|
|
|
|
26. |
| Construct the inscribed regular 30-sided polygon of circle 14, pointing up.
|
|
27. |
| Draw the thirty rays of circle 14, to the angular points of polygon 26.
|
|
28. |
| Remove all parts from circles 14 and 16, and lines 27, such that the shown pattern remains.
|
|
|
|
29. |
| Circles 3, 4, and 19, and patterns 22, 25, and 28, are used for the final reconstruction.
|
|
30. |
| Remove all parts not visible within the formation itself.
|
|
31. |
| Colour all areas corresponding to standing...
|
|
32. |
| ...or to flattened crop, and finish the reconstruction of the 2018 Hackpen Hill (3) formation.
|
|
33. |
| The final result, matched with the aerial image.
