2007 Chute Causeway formation
|
Reconstruction of the 2007 Chute Causeway 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 a circle, passing through the center of circle 1, and passing through the upper lefthand and righthand angular points of pentagon 2. |
| 4. |
| Construct the inscribed pentagon of circle 3, pointing up. |
| 5. |
| Construct the inscribed pentagram (regular 5-pointed star) of circle 3, by drawing all diagonals of pentagon 4. |
| 6. |
| Construct the circumscribed circle of the pentagon enclosed by pentagram 5, as shown. |
| 7. |
| Construct the circumscribed pentagon of circle 6, pointing up. |
| 8. |
| Construct the inscribed circle of pentagon 4. |
| 9. |
| Construct a "two-points" circle, defined by the end-points of a centerline, with one point at the upper intersection of circle 6 and the vertical centerline, the other point at the top of pentagon 7. |
| 10. |
| Copy circle 9 to the upper intersection of circle 8 and the vertical centerline. |
| 11. |
| Construct a circle concentric to circle 8, tangent to circle 10 at the lower side. |
| 12. |
| Extend all sides of pentagon 7 in both directions up to circle 8. |
| 13. |
| Copy circle 9 four times, to the four upper intersections of circle 11 and lines 12. |
| 14. |
| Copy circle 9 another six times, to all other intersections of circle 11 and lines 12. |
| 15. |
| Copy pentagram 5 and circles 13 and 14 as a whole from its lower lefthand to its upper righthand angular point, as shown. |
| 16. |
| Copy pattern 15 (pentagram and circles) from its upper lefthand to its upper righthand angular point. |
| 17. |
| Copy pattern 15 from its lower righthand angular point to its top. |
| 18. |
| Copy pattern 16 from its lower lefthand angular point to its top. |
| 19. |
| Copy pattern 17 from its lower lefthand to its upper righthand angular point. |
| 20. |
| Patterns 15, 16, 17, 18 and 19 make up the upper righthand part of the formation; remove all (inner) elements not present in the formation. |
| 21. |
| Copy pattern 20 four times, and distribute them, while rotating, evenly around pentagon 2, to the corresponding positions with respect to its angular points, as shown. |
| 22. |
| Copy pentagram 5 and circles 13 as a whole four times, and distribute them, while rotating, evenly around the center of circle 1, to the corresponding positions with respect to the sides of pentagon 2, as shown. |
| 23. |
| Copy circle 9 to the top of the pentagon enclosed by pentagrams 5 and 22, as shown. |
| 24. |
| Construct a circle concentric to circle 1, tangent to circle 23 at the lower side. |
| 25. |
| Construct the circumscribed pentagon of circle 24, pointing down. |
| 26. |
| Copy circle 9 five times, to the angular points of pentagon 25. |
| 27. |
| Pentagram 5, circles 13 and 26, and patterns 20, 21 and 22, are used for the final reconstruction. |
| 28. |
| Remove all superfluous parts, not present in the formation itself. |
| 29. |
| Colour all areas corresponding to standing... |
| 30. |
| ...or to flattened crop, and finish the reconstruction of the 2007 Chute Causeway formation. |
| 31. |
| The final result, matched with the aerial image. |
