Reconstruction of theGreen Street 29-07-2014 formation 1. Draw a circle. Draw and extend the horizontal and vertical centerlines. 2. Construct the inscribed regular 13-sided polygon of circle 1, pointing down. 3. Construct the inscribed circle of polygon 2. 4. Construct the circumscribed regular 13-sided polygon of circle 1, pointing up. 5. Construct a circle centered at the mid-point of the lower side of polygon 4, passing through the lowest righthand angular point. 6. Copy circle 5 to the lower intersection of circle 3 and the vertical centerline. 7. Draw the connecting line between the intersections of circles 3 and 6. 8. Construct a circle centered at the righthand intersection of circle 6 and the lower side of polygon 4, passing through the righthand intersection of circles 1 and 6. See detail. 9. Copy circle 8 to the intersection of line 7 and the vertical centerline. 10. Construct a circle centered at the righthand intersection of circles 3 and 6, tangent to circle 9 at the righthand side. 11. Construct a circle concentric to circle 6, passing through the righthand intersection of circles 3 and 10. 12. Copy circle 11 twelve times, six to the left, six to the right. The first to the lefthand intersection of circles 3 and 11, then five consecutively to the corresponding intersections, the next one to the righthand intersection of circles 3 and 11, and finally five consecutively to the corresponding intersections, as shown. 13. Copy circle 6 twelve times, to the centers of circles 12. 14. Copy circle 10 two times, to the centers of the upper lefthand and righthand circles 13. 15. Draw two lines, from the center of circle 1, tangent to circles 14 at the inner sides (closest to the vertical centerline), and extend these lines upto circle 3. 16. Copy circle 11 to the center of circle 5. 17. Construct a circle concentric to circle 1, tangent to circle 16 at the upper side. 18. Construct a circle centered at the upper intersection of circle 11 and the vertical centerline, tangent to circle 16 at the upper side. 19. Construct a circle concentric to circle 1, tangent to circle 18 at the upper side. 20. Copy circle 5 to the center of circle 1. 21. Construct a circle concentric to the upper righthand circle 13, passing through the righthand intersection of the upper lefthand circle 13 and circle 1. 22. Construct a circle concentric to the upper righthand circle 13, tangent to the lefthand circle 14 at the righthand side. 23. Construct a circle centered at the intersection of lefthand line 15 and circle 20, passing through the upper intersection of circle 20 and the vertical centerline. 24. Copy circle 23 to the center of circle 1. 25. Construct a line tangent to circles 23 and 24 at the righthand sides, and extend this line down to circle 20. 26. Construct a circle centered at the lower intersection of circle 19 and the vertical centerline, tangent to circle 17 at the lower side. 27. Copy circle 26 to the center of circle 1. 28. Copy circles 21 and 22 to the lower intersection of circle 27 and line 25. 29. Construct a circle centered at the upper intersection of circle 26 and the vertical centerline, passing through the center of circle 18. 30. Copy circle 29 to the intersection of righthand line 15 and inner circle 28. 31. Circles 1, 3, 6, 13, 17, 19, 20, 28 and 30, and lines 15, are used for the final reconstruction. 32.
