Reconstruction of theLongwood Warren 10-07-2018 formation | |||||

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

2. |
Construct the inscribed nonagon (regular 9-sided polygon) of circle 1, pointing down. Draw the nine rays of circle 1 to the angular points. Number the angular points, as well as the rays clockwise 1 - 9, starting at the top right. | ||||

3. |
Draw nine diagonals of nonagon 2, between the following pairs of angular points: 1-4, 2-5, 3-6, 4-7, 5-8, 6-9, 7-1, 8-2, 9-3. | ||||

4. |
Construct the circumscribed nonagon of circle 1, pointing up. | ||||

5. |
Draw the connecting line between the top left and top right angular points of nonagon 4. | ||||

6. |
Construct a circle centered at the intersection of line 5 and the vertical centerline, tangent to diagonals 3 1-4 and 6-9. | ||||

7. |
Copy circle 6 to the center of circle 1. | ||||

8. |
Construct the "two-points" circle (defined by the two end-points of a centerline) between the upper intersection of circle 7 and the lower intersection of circle 1, with the vertical centerline. | ||||

9. |
Construct a circle concentric to circle 8, tangent to the lowest sides of nonagon 2. | ||||

10. |
Construct a circle centered at the (lefthand) intersection of circle 8 and the lowest lefthand side of nonagon 2, passing through the righthand intersection of circle 9 and diagonal 3 3-6. | ||||

11. |
Construct a circle concentric to circle 1, tangent to circle 10 at the near side. | ||||

12. |
Construct a circle centered at the intersection of diagonals 3 7-1 and 9-3, tangent to rays 2 nrs. 1 and 9. | ||||

13. |
Copy circle 12 to the center of circle 1. | ||||

14. |
Construct a circle concentric to circle 8, passing through the intersection of diagonal 3 1-4 and the horizontal centerline. | ||||

15. |
Copy circle 8 eight times, to the corresponding positions with respect to the other rays 2. | ||||

16. |
Copy circle 9 eight times, to the corresponding positions with respect to the other rays 2. | ||||

17. |
Copy circle 14 eight times, to the corresponding positions with respect to the other rays 2. | ||||

18. |
Copy circle 10 eight times, to the corresponding positions with respect to the other sides of nonagon 2. | ||||

19. |
Remove all parts from circles 8 and 15, such that the shown pattern remains. | ||||

20. |
Remove all parts from circles 8, 9, 14, 15, 16, and 17, such that the shown patterns remain. | ||||

21. |
Remove all parts from circles 7, 9, 10, 16, and 18, such that the shown patterns remain. | ||||

22. |
Circles 11, and 13, and patterns 19, 20, and 21, together, make up the final reconstruction. pdf-file | ||||
