2013 Chute Causeway formation
|
Reconstruction of the 2013 Chute Causeway formation | ||
| 1. |
| Draw a circle. Draw the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed hexagon (regular six-sided polygon) of circle 1, pointing to the right. |
| 3. |
| Draw the two upper rays of hexagon 2. |
| 4. |
| Construct the inscribed circle of the triangle formed by the two rays 3 and the upper side of hexagon 2. |
| 5. |
| Copy circle 4 to its upper intersection with the vertical centerline. |
| 6. |
| Draw two lines from the center of circle 1 to the intersections of circles 4 and 5, and extend these lines upto the upper side of hexagon 2. Call the righthand intersection with this side point A and the lefthand one point B. |
| 7. |
| Construct a circle concentric to circle 1, passing through A. |
| 8. |
| Construct the inscribed hexagon of circle 7, pointing up. |
| 9. |
| Draw two lines, from A to the lower lefthand, and from B to the lower righthand angular points of hexagon 8. |
| 10. |
| Construct a circle concentric to circle 1, passing through the intersection of lines 9. |
| 11. |
| Construct a circle centered at the intersection of the upper righthand side of hexagon 8 and line 9, tangent to the upper side of hexagon 2. |
| 12. |
| Copy circle 11 to the intersection of lines 9. |
| 13. |
| Draw the connecting line between the leftmost intersections of circle 7 and the lefthand sides of hexagon 2. |
| 14. |
| Construct a circle centered at the intersection of line 13 and the horizontal centerline, tangent to circle 7 at the near side. |
| 15. |
| Copy circle 14 to the center of circle 12. |
| 16. |
| Construct a circle concentric to circle 1, tangent to circle 15 at the lower side. |
| 17. |
| Remove all redundant parts from lines 6 and 9, and from circles 10, 12 and 16, such that the shown pattern remains. |
|
| ||
| 18. |
| Copy this pattern (repeat all necessary steps) five times, from the top of hexagon 8 to the other angular points, while rotating around the center. |
| 19. |
| Circle 1, and patterns 17 and 18, together make up the final reconstruction. |
| 20. |
| Colour all areas corresponding to standing... |
| 21. |
| ...or to flattened crop, and finish the reconstruction of the 2013 Chute Causeway formation. |
| 22. |
| The final result, matched with the aerial image. |
