Reconstruction of the2001 Chilcomb Down formation |
|||||

1. |
Draw a circle. | ||||

2. |
Draw the horizontal and vertical centerlines. | ||||

3. |
Construct a pentagon (regular 5-sided polygon) inscribed in circle 1, with one angular point pointing to the left. | ||||

4. |
Construct the inscribed pentagram by drawing all diagonals of pentagon 3. | ||||

5. |
Construct the circle inscribed in pentagram 4 (tangent to all diagonals). | ||||

6. |
Construct an octagon (regular 8-sided polygon) inscribed in circle 1, with angular points at the end-points of both centerlines. | ||||

7. |
Construct the inscribed circle of octagon 6. | ||||

8. |
Construct the circumscribed pentagon of circle 7, pointing to the left. | ||||

9. |
Construct the circumscribed circle of pentagon 8. | ||||

10. |
Construct the circumscribed decagon (regular 10-sided polygon) of circle 9, pointing upward. | ||||

11. |
Construct the circumscribed circle of decagon 10. | ||||

12. |
Construct the inscribed equilateral triangle of circle 1, pointing to the left. | ||||

13. |
Construct a circle concentric with circle 1, with a radius determined by the intersection of equilateral triangle 12 and pentagram 4, as shown. | ||||

14. |
Construct the circumscribed pentagon of circle 13, pointing to the left. | ||||

15. |
Construct the circumscribed circle of pentagon 14. | ||||

16. |
Construct the inscribed decagon of circle 15, with angular points at the horizontal centerline. Elongate two sides of the decagon, two apart, until they intersect, see figure. | ||||

17. |
Construct a circle concentric with circle 1, with a radius determined by the intersection of both elongated sides of decagon 16, as shown. | ||||

18. |
Going back to pentagon 8, construct the inscribed pentagram by drawing the diagonals. | ||||

19. |
This pentagram includes a smaller pentagon. Construct the inscribed pentagram of this smaller pentagon, again by drawing its diagonals. | ||||

20. |
Construct the inscribed circle of pentagram 19. | ||||

21. |
Going back to circle 5, construct the inscribed pentagon, pointing to the left. | ||||

22. |
Construct the inscribed circle of pentagon 21. | ||||

23. |
Similar to pentagrams 18 and 19, construct the inscribed pentagram of pentagram 4. | ||||

24. |
Construct the (small) inscribed circle of pentagram 23. | ||||

25. |
Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, with angular points at the horizontal centerline. | ||||

26. |
Construct the inscribed circle of hexagon 25. | ||||

27. |
From the end-point on the right of the horizontal centerline of circle 1, construct two lines, tangent to circle 24 at both sides, as shown. | ||||

28. |
Copy lines 27 four times and rotate each pair equally around the circle (the angular points fall exactly in between those of pentagram 4). | ||||

29. |
Construct five (small) circles with centers at intersections of the (right half of the) horizontal centerline and circles 13, 15, 17, 26 and 7, respectively, each tangent to both lines 27, as shown. | ||||

30. |
Repeat this for the copied pairs of lines (28). | ||||

31. |
Construct a (small) circle with its center at the intersection of the (left half of the) horizontal centerline and circle 26, tangent to two adjacent sides of pentagram 4, as shown. | ||||

32. |
Repeat this for the other pairs of sides of pentagram 4. | ||||

33. |
Copy the middle circle of circles 29 to the intersection of the horizontal centerline (on the right) and circle 22, as shown. | ||||

34. |
Construct two parallel lines tangent to both circles 33 (the copied and its original one), as shown. | ||||

35. |
Repeat this for the other sets of circles (30). | ||||

36. |
Circles 1, 5, 9, 11, 20 and 22, circle sets 30 and 32, pentagram 4, and lines 35 together form all ingredients for the final reconstruction. | ||||

37. |
Leaving out everything not needed any more, and making black all areas corresponding to standing crop, finishes the reconstruction of the 2001 Chilcomb Down formation. | ||||
