Reconstruction of the 2014 Ammersee (D) formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed equilateral triangle of circle 1, pointing up. |
| 3. |
| Construct the inscribed circle of triangle 2. |
| 4. |
| Construct the inscribed equilateral triangle of circle 3, pointing down. |
| 5. |
| Copy circle 3 to the lower angular point of triangle 4. |
| 6. |
| Construct the inscribed regular 24-sided polygon of circle 3, pointing down. Number the angular points counterclockwise 1 - 24, starting with the lowest. |
| 7. |
| Construct a circle concentric to circle 5, passing through angular point 6 nr. 4. |
| 8. |
| Copy circle 7 two times, to the lefthand and righthand angular points of triangle 4. |
| 9. |
| Construct a circle concentric to circle 5, tangent to the righthand circle 8 at the lower lefthand side. |
| 10. |
| Construct a circle concentric to circle 5, passing through angular point 6 nr. 3. |
| 11. |
| Construct a circle concentric to circle 5, passing through angular point 6 nr. 2. |
| 12. |
| Copy circles 9, 10 and 11 two times, to the centers of circles 8. |
| 13. |
| Copy circle 5 twentythree times, to angular points 6 nrs. 2 - 24. |
| 14. |
| Construct the circumscribed octagon (regular 8-sided polygon) of circle 1, with the midpoint of a side at the lower intersection of circle 1 and the vertical centerline. |
| 15. |
| Construct the circumscribed circle of octagon 14. |
| 16. |
| Circles 3, 5, 7, 8, 9, 10, 11, 12, 13 and 15, are used for the final reconstruction. |
| 17. |
| Remove all parts not visible within the formation itself. |
| 18. |
| Colour all areas corresponding to standing... |
| 19. |
| ...or to flattened crop, and finish the reconstruction of the 2014 Ammersee (D) formation. |
| 20. |
| The final result, matched with the aerial image. |
