|
Reconstruction of the 2005 Bishop's Sutton formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the circumscribed octagon (regular 8-sided polygon) of circle 1, with the midpoint of one side coincident with the righthand intersection of circle 1 and the horizontal centerline, as shown. |
| 3. |
| Construct the circumscribed circle of octagon 2. |
| 4. |
| Draw the two rays from the center of circle 1 to the righmost two angular points of octagon 2, as shown. |
| 5. |
| Construct the inscribed circle of the triangle formed by rays 4 and the rightmost side of octagon 2. |
| 6. |
| Copy circle 5 to the righthand intersection of circle 3 and the horizontal centerline. |
| 7. |
| Draw a line from the upper intersection of circles 5 and 6 to the right, parallel to the horizontal centerline. |
| 8. |
| Construct a circle centered at the intersection of circle 1 and line 7, tangent to circle 5 at the near side. |
| 9. |
| Copy circle 8 to the righthand intersection of circle 6 and line 7. |
| 10. |
| Construct a circle concentric to circle 6, tangent to circle 9 at the far side. |
| 11. |
| Copy circle 10 to the center of circle 9. |
| 12. |
| Construct a circle centered at the intersection of the rightmost side of octagon 2 and line 7, tangent to circle 8 at the righthand side. |
| 13. |
| Copy circle 12 to the righthand intersection of circle 11 and line 7. |
| 14. |
| Circles 1, 3, 9 and 13 together make up the reconstruction of the formation. |
| 15. |
| The reconstruction of the 2005 Bishop's Sutton formation is completed by colouring the area corresponding to standing... |
| 16. |
| ...or to flattened crop. |
| 17. |
| The final result, matched with the aerial image. |
