Considering the previous combinations, which were obtained by the rotation of the hexagram, pentagram and octagon, we could see that the values of many azimuths are close to the whole end namely to 10 and 5. This means that in the point of Great Zimbabwe (GZ) azimuths dispose multiply to 10 and 5 degrees from the north-south axis.
Orient one octagon along the cardinal points and the other one shift on 10 * from the north-south axis. So we divide the circumference by 10 *.
In such position it can be clearly seen that the azimuths of 6 objects are located around the (GZ) multiply to 10 *. The error you can easily identify yourself as the exact value of azimuth must end on 0.00 *.
Now turn one nonagon on 5 * clockwise and the other one on 5 * counterclockwise Thus, we again divide the circumference by 10 *, but with an offset on 5 * clockwise.
In such position we find that another 7 azimuths located around GZ multiply to 10 *. In this case, the exact values of azimuth must end one 5.00 *.
If you simultaneously include both combinations on interactive map at the end of the page, you will see that azimuths of 13 main points of system, with an accuracy less than half a degree located around the GZ multiply to 5 *.
In this combination it can be include one more azimuth of Plain of Jars, which is equal to 65.34 *. Together with GZ and Sigiriya this mysterious object lies on the same line.
Consider another interesting combination, which form azimuths of Nan Madol, Uluru and Vera island. With this purpose turn octagon on 3 * counterclockwise.
In this position we, with an error + 0.02 *, obtain azimuth of Nan Madol from which is away on 20 * direction to Uluru. Angle between the directions is 20.14 *, the error is + 0.14 *.
Between azimuths of Faith island and Nan Madol are 80.6 *, the error is + 0.6 *.
