2018 Martinsell Hill formation
|
Reconstruction of the 2018 Martinsell Hill 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. |
| Draw the five diagonals of pentagon 2. |
| 4. |
| Draw the five diagonals of the pentagon enclosed by diagonals 3, and extend these lines upto pentagon 2 in both directions. Number the intersections with pentagon 2 clockwise 1 - 10, starting at the top left. |
| 5. |
| Draw the five diagonals of the pentagon enclosed by diagonals 4, and extend these lines upto pentagon 2 in both directions. Number the intersections with pentagon 2 clockwise 11 - 20, starting at the top left. |
| 6. |
| Draw five connecting lines between the following pairs of numbered intersections: 11 and 18, 12 and 15, 13 and 20, 14 and 17, and 16 and 19. |
| 7. |
| Draw five connecting lines between the following pairs of numbered intersections: 1 and 8, 2 and 5, 3 and 10, 4 and 7, and 6 and 9. |
| 8. |
| Draw five connecting lines between the following pairs of numbered intersections: 1 and 4, 2 and 9, 3 and 6, 5 and 8, and 7 and 10. |
| 9. |
| Complete the ten small, peripheral pentagrams (regular 5-pointed stars) by drawing every three respective connecting lines, as shown. See detail. |
|
| ||
| 10. |
| Complete the five small pentagrams, in between pentagrams 9, by drawing every two respective connecting lines, as shown. See detail. |
|
| ||
| 11. |
| Construct the circumscribed circle of the pentagon enclosed by lines 5. See detail. |
|
| ||
| 12. |
| Copy circle 11 to the upper intersection of circle 1 and the vertical centerline. |
| 13. |
| Construct a circle concentric to circle 1, tangent to circle 12 at the upper side. |
| 14. |
| Circle 13, and lines 3, 4, 5, 6, 7, 8, 9, and 10, are used for the final reconstruction. |
| 15. |
| Remove all parts not visible within the formation itself. |
| 16. |
| Colour all areas corresponding to standing... |
| 17. |
| ...or to flattened crop, and finish the reconstruction of the 2018 Martinsell Hill formation. |
| 18. |
| The final result, matched with the aerial image. |
