Reconstruction of the 2022 Etchilhampton Hill (2) formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed pentagon (regular 5-sided polygon) of circle 1, pointing down. |
| 3. |
| Construct the inscribed pentagon (of the inscribed circle) of pentagon 2, pointing up. |
| 4. |
| Construct the inscribed pentagon of pentagon 3, pointing down. |
| 5. |
| Construct the inscribed pentagon of pentagon 4, pointing up. |
| 6. |
| Construct the inscribed pentagon of pentagon 5, pointing down. |
| 7. |
| Construct the inscribed pentagon of pentagon 6, pointing up. |
| 8. |
| Construct the inscribed pentagon of pentagon 7, pointing down. |
| 9. |
| Construct the inscribed circle of pentagon 8. |
| 10. |
| Construct a circle centered at the lower righthand angular point of pentagon 8, tangent to the vertical centerline. |
| 11. |
| Copy circle 10 to the lower angular point of pentagon 2. |
| 12. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the upper intersections of circles 9 and 11 with the vertical centerline. |
| 13. |
| Copy circle 9 to the center of circle 11. |
| 14. |
| Construct a circle concentric to circle 12, tangent to circle 13 at the upper side. |
| 15. |
| Construct a circle concentric to circle 9, tangent to circle 14 at the upper side. |
| 16. |
| Construct a "two-points" circle between the lower intersections of circles 11 and 15 with the vertical centerline. |
| 17. |
| Construct a circle concentric to circle 16, tangent to circle 13 at the lower side. |
| 18. |
| Construct a circle centered at the upper intersection of pentagon 8 and the vertical centerline, passing through its upper righthand angular point. |
| 19. |
| Copy circle 18 to the center of circle 1. |
| 20. |
| Copy circles 11, 12, 14, 16, and 17, as a whole, four times, while rotating around the center of circle 1, with respect to the other angular points of pentagon 2. |
| 21. |
| Circles 11, 12, 14, 15, 16, 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 2022 Etchilhampton Hill (2) formation. |
| 25. |
| The final result, matched with two aerial images. |
