Reconstruction of the
Hackpen Hill (2) 23-06-2018 formation

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

2. Copy circle 1 to its upper intersection with the vertical centerline.

3. Construct the circumscribed pentagon (regular 5-sided polygon) of circle 2, pointing up.

4. Extend the lower righthand side of pentagon 3 downto the vertical centerline.

5. Construct a circle concentric to circle 2, passing through the intersection of line 4 and the vertical centerline.

6. Construct the inscribed pentagon of circle 5, pointing down.

7. Draw the five diagonals of pentagon 6.

8. Construct a circle centered at the upper (inner) intersection of diagonals 7, tangent to the upper side of pentagon 6.

9. Construct a line passing through the center of circle 2, parallel to the horizontal centerline, and extending upto circle 5 in both directions.

10. Construct the circumscribed decagon (regular 10-sided polygon) of circle 5, pointing up.

11. Construct the circumscribed circle of decagon 10.

12. Construct a circle concentric to circle 8, tangent to circle 11 at the lower side.

13. Construct the circumscribed pentagon of circle 5, pointing down.

14. Construct a circle concentric to circle 8, passing through the lower angular point of pentagon 13.

15. Construct a circle concentric to circle 1, tangent to circle 14 at the upper side.

16. Construct a circle centered at the intersection (tangent point) of circles 14 and 15, tangent to circle 12 at the upper side.

17. Construct a circle concentric to circle 1, tangent to circle 16 at the upper side.

18. Circles 11, 12, 14, 15, and 17, and lines 7, together, make up the final reconstruction.
