2016 Ranscomb Bottom formation
|
Reconstruction of the 2016 Ranscomb Bottom formation | ||
| 1. |
| Draw a circle. Draw the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed pentagon (regular 5-sided polygon) of circle 1, pointing up. |
| 3. |
| Draw the five diagonals of pentagon 2. Number these diagonals clockwise 1 - 5, starting at the horizontal one. |
| 4. |
| Construct the inscribed pentagon of circle 1, pointing down. Number the sides clockwise 1 - 5, starting at the upper one. |
| 5. |
| Construct the circumscribed pentagon of circle 1, the lower side horizontally. |
| 6. |
| Extend the sides of pentagon 2 each in both directions upto pentagon 5. |
| 7. |
| Construct the inscribed decagon (regular 10-sided polygon) of circle 1, by connecting the successive angular points of pentagons 2 and 5. |
| 8. |
| Draw the five diagonals of the pentagon enclosed by diagonals 3. |
| 9. |
| Draw the five diagonals of pentagon 4. |
| 10. |
| Draw the connecting line between the intersection of diagonal 3 nr. 5 and side 4 nr. 1 and the intersection of diagonal 3 nr. 1 and side 4 nr. 5. Repeat this four times for the other corresponding intersections of diagonals 3 and sides 4, as shown. |
| 11. |
| Draw the two diagonals of the lower righthand parallelogram enclosed by pentagon 5 and lines 6. |
| 12. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the intersection of the upper lefthand and upper righthand diagonals 9 and the intersection of diagonal 3 nr. 1 and the vertical centerline. |
| 13. |
| Copy circle 12 to the intersection of diagonals 11. |
| 14. |
| Copy circle 12 four more times to the other positions with respect to pentagon 5 corresponding to circle 13, as shown. |
| 15. |
| Lines 3, 4, 5, 6, 7, 8, 9, and 10, and circles 13 and 14, are used for the final reconstruction. |
| 16. |
| Remove all parts not visible within the formation itself. |
| 17. |
| Colour all areas corresponding to standing... |
| 18. |
| ...or to flattened crop, and finish the reconstruction of the 2016 Ranscomb Bottom formation. |
| 19. |
| The final result, matched with two aerial images. |
