Reconstruction of theHackpen 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. pdf-file | ||||
