Reconstruction of the
2021 Little Nutford formation |
|
1. |
| Draw a circle. Draw the horizontal and vertical centerlines.
|
|
2. |
| Construct the inscribed pentagon (regular five-sided polygon) of circle 1, pointing down.
|
|
3. |
| Draw the connecting line between the upper intersection of circle 1 and the vertical centerline and the upper lefthand angular point of pentagon 2.
|
|
4. |
| Construct a circle concentric to circle 1, tangent to line 3.
|
|
5. |
| Construct a circle centered at the lower angular point of pentagon 2, passing through its righthand angular point.
|
|
6. |
| Construct a circle centered at the righthand angular point of pentagon 2, passing through its lower angular point.
|
|
7. |
| Construct a circle centered at the lefthand angular point of pentagon 2, passing through its lower angular point.
|
|
8. |
| Construct a circle centered at the upper righthand angular point of pentagon 2, passing through its upper lefthand angular point.
|
|
9. |
| Construct a circle centered at the upper lefthand angular point of pentagon 2, passing through its upper righthand angular point.
|
|
10. |
| Construct a circle concentric to circle 1, passing through the righthand intersection of circle 5 and the horizontal centerline.
|
|
11. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the upper intersections of circle 5 with circles 6 and 7.
|
|
12. |
| Copy circle 11 to the center of circle 1.
|
|
13. |
| Construct a circle centered at the upper intersection of circles 6 and 7, tangent to circle 10 at the upper side.
|
|
14. |
| Copy circle 13 to the center of circle 1.
|
|
15. |
| Construct the inscribed pentagon of circle 14, pointing up.
|
|
16. |
| Construct a circle tangent to the upper righthand side of pentagon 15 at the outside, and tangent to circles 5 and 7 at the insides, as shown.
|
|
17. |
| Copy circle 16 five times, to the angular points of pentagon 15.
|
|
18. |
| Construct a "two-points" circle between the lower intersections of circles 1 and 4 with the vertical centerline.
|
|
19. |
| Construct a circle concentric to circle 6, passing through the center of circle 18.
|
|
20. |
| Copy circle 19 four times, to the centers of circles 5, 7, 8, and 9.
|
|
21. |
| Circles 1, 4, 5, 6, 7, 8, 9, 10, 12, 17, 19, and 20, are used for the final reconstruction.
|
|
22. |
| Remove all parts not visible within the formation itself.
|
|
23. |
| Colour all areas corresponding to standing...
|
|
24. |
| ...or to flattened crop, and finish the reconstruction of the 2021 Little Nutford formation.
|
|
25. |
| The final result, matched with the aerial image.
