Reconstruction of the 2017 Hackpen Hill formation | ||

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

2. |
Construct the inscribed dodecagon (regular 12-sided polygon) of circle 1, pointing up. | |

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

4. |
Construct the inscribed hexagon (regular 6-sided polygon) of circle 3, pointing to the right. | |

5. |
Construct the inscribed hexagon of circle 3, pointing up. | |

6. |
Draw twelve rays, from the center of circle 1 to the angular points of hexagons 4 and 5. | |

7. |
Construct the inscribed equilateral triangle of circle 3, pointing to the left. | |

8. |
Construct the inscribed equilateral triangle of circle 3, pointing to the right. | |

9. |
Construct a circle centered at the midpoint of the righthand side of triangle 7, tangent to the righthand side of hexagon 5. | |

10. |
Copy circle 9 to the center of circle 1. | |

11. |
Construct the inscribed dodecagon of circle 10, pointing up. | |

12. |
Draw two lines, from the upper intersection of triangles 7 and 8 to the upper lefthand and righthand angular points of dodecagon 11. | |

13. |
Repeat step 12 five times, with respect to the other intersections of triangles 7 and 8, and the corresponding angular points of dodecagon 11, as shown. | |

14. |
Construct a circle centered at the top of dodecagon 11, passing through its upper righthand angular point. | |

15. |
Copy circle 14 six times, to the angular points of hexagon 5. | |

16. |
Circles 1, 3, and 15, lines 6, 12, and 13, triangles 7 and 8, and dodecagon 11, 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 2017 Hackpen Hill formation. | |

20. |
The final result, matched with the aerial image. |
