2017 Waden Hill formation
|
Reconstruction of the 2017 Waden Hill formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing up. |
| 3. |
| Construct a circle centered at the top of hexagon 2, tangent to circle 1 at the lower side. |
| 4. |
| Copy circle 3 five times, to the other angular points of hexagon 2. |
| 5. |
| Construct a circle passing through the inner mutual intersections of circles 3 and 4. |
| 6. |
| Construct a circle concentric to circle 3, tangent to circle 5 at the lower side. |
| 7. |
| Copy circle 6 five times, to the centers of circles 4. |
| 8. |
| Construct a circle centered at the righthand intersection of circle 1 and the horizontal centerline, tangent to circle 5 at the righthand side. |
| 9. |
| Construct a circle concentric to circle 1, tangent to circle 8 at the lefthand side. |
| 10. |
| Construct a circle concentric to circle 3, tangent to circle 9 at the lower side. |
| 11. |
| Copy circle 10 five times, to the centers of circles 4. |
| 12. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 8 and its lefthand intersection with the horizontal centerline. |
| 13. |
| Copy circle 12 four times, to the center of circle 1 and to the lower and the upper lefthand and righthand angular points of hexagon 2. |
| 14. |
| Construct three pairs of parallel lines, each tangent to the outer circles 13, and all to the central one, all at both sides, as shown. |
| 15. |
| Circles 3, 4, 5, 6, 7, 10, and 11, hexagon 2, and lines 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 2017 Waden Hill formation. |
| 19. |
| The final result, matched with the aerial image. |
