2009 Morgan's Hill formation
|
Reconstruction of the 2009 Morgan's Hill formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Copy circle 1 to its upper intersection with the vertical centerline, and move this circle (copy and delete original) to its own corresponding intersection. |
| 3. |
| Construct a circle concentric to circle 1, tangent to circle 2 at the upper side. |
| 4. |
| Construct the inscribed hexagon (regular 6-sided polygon) of circle 3, pointing up. |
| 5. |
| Copy circle 1 to the upper angular point of hexagon 4. |
| 6. |
| Copy circle 1 two times, to the lower lefthand and righthand angular points of hexagon 4. |
| 7. |
| Copy circle 1 three times, to the three other angular points of hexagon 4. |
| 8. |
| Copy circle 1 to the upper intersection of circle 5 and the vertical centerline, and move it to its own corresponding intersection. |
| 9. |
| Copy circle 1 to the upper intersection of circle 8 and the vertical centerline. |
| 10. |
| Construct a circle concentric to circle 1, passing through the center of circle 9. |
| 11. |
| Construct the inscribed equilateral triangle of circle 10, pointing up. |
| 12. |
| Copy circle 1 two times, to the lower lefthand and righthand angular points of triangle 11. |
| 13. |
| Construct a "two-points" circle (defined by the end-points of a centerline), between the righthand intersections of hexagon 4 and circle 3 with the horizontal centerline. |
| 14. |
| Construct a "two-points" circle between the center of circle 13 and the righthand intersection of circle 3 and the horizontal centerline. |
| 15. |
| Copy circle 14 to the center of circle 5. |
| 16. |
| Construct a circle concentric to circle 1, tangent to circle 15 at the lower side. |
| 17. |
| Construct a circle concentric to circle 1, tangent to circle 15 at the upper side. |
| 18. |
| Copy circle 14 to the center of circle 9. |
| 19. |
| Construct two parallel lines, tangent to circles 15 and 18 at both sides. |
| 20. |
| Repeat steps 15, 18 and 19 two times, for the corresponding pairs of circles 6 and 12, as shown. |
| 21. |
| Circles 1, 5, 6, 7, 9, 12, 16 and 17, and lines 19 and 20, are used for the final reconstruction. |
| 22. |
| Remove all redundant parts not visible within the formation itself. |
| 23. |
| Colour all areas corresponding to standing... |
| 24. |
| ...or to flattened plants, and finish the reconstruction of the 2009 Morgan's Hill formation. |
| 25. |
| The final result, matched with the aerial image. |
