Reconstruction of the 2017 Oxleaze Copse formation | ||

1. |
Draw a circle. Draw the horizontal and vertical centerlines. | |

2. |
Construct the inscribed decagon (regular 10-sided polygon) of circle 1, pointing up. | |

3. |
Construct the inscribed circle of decagon 2. | |

4. |
Construct the inscribed equilateral triangle of circle 3, pointing up. | |

5. |
Construct the inscribed equilateral triangle of circle 3, pointing to the left. | |

6. |
Draw a line from the center of circle 1 to the upper intersection of triangles 4 and 5. Extend this line upto circle 3. | |

7. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the top of triangle 4 and the intersection of circle 3 and line 6. | |

8. |
Draw a line between the centers of circles 1 and 7. Extend this line upto circle 3. | |

9. |
Construct the inscribed regular 24-sided polygon of circle 3, with one angular point coincident with the intersection of line 8 and circle 3. | |

10. |
Construct a circle centered at the upper intersection of circle 1 and the vertical centerline, passing through the second angular point of polygon 9, to the right from the top of triangle 4, as shown. | |

11. |
Copy circle 10 to the center of circle 1. | |

12. |
Construct the larger circle, passing through the upper intersection of circle 11 and the vertical centerline, tangent to the lefthand and to the righthand sides of triangle 4, as shown. | |

13. |
Draw twenty-four rays, from the center of circle 12 to the angular points of polygon 9. | |

14. |
Construct a circle centered at the upper intersection of circle 3 and the vertical centerline, tangent to circle 1 at the upper side. | |

15. |
Copy circle 14 to the upper intersection of circle 11 and the vertical centerline. | |

16. |
Construct a circle concentric to circle 11, tangent to circle 15 at the lower side. | |

17. |
Construct a circle concentric to circle 12, tangent to circle 15 at the lower side. | |

18. |
Construct a circle centered at the lower intersection of circle 14 and the vertical centerline, tangent to its upper side. | |

19. |
Copy circle 18 to the center of circle 12. | |

20. |
Circles 1, 3, 11, 12 16, 17, and 19, and lines 13, are used for the final reconstruction. | |

21. |
Remove all parts not visible within the formation itself. | |

22. |
Colour all areas corresponding to standing... | |

23. |
...or to flattened crop, and finish the reconstruction of the 2017 Oxleaze Copse formation. | |

24. |
The final result, matched with the aerial image. |
