In Nazca nonagon gives several unique combinations at its turning close to 7 degrees.
Turn one nonagon on 7.5 degrees clockwise and other one on 7.5 degrees counter-clockwise and one more on 2.5 counter-clockwise i.e. we will divide the circumference multiply to 5-degrees.
In such position can be clearly seen that the azimuths of 11 objects located relatively to each other multiply to 5 degrees.
In this case, we can say that we superpose nonagon exactly with the direction to Tiwanaku and all the others count out from it. Then the minimum errors will have azimuths Uluru and of Nan Madol.
Now having an overall picture of main azimuths locations consider a few more positions of nonagon.
We divide the circumference by 10 degrees, turning nonagon on 7 and 3 degrees.
In this position, we see that to the directions to Tiwanaku and Nan Madol joins azimuth of Stonehenge.
The angle between Stonehenge and Tiwanaku is 70 degree with an error +0.56. And angle between Nan Madol and Stonehenge is 50 degree. (+0.59).
Then turn nonagon on 3.3 degrees clockwise.
In this position it is perfectly clear that from the Super Line - Easter island -The Great Pyramid (GP) which passes right through the desert of Nazca multiply 20 degrees located azimuths of Lalibela and Sigiriya with very high precision.
Turning octagon on 1.2 degree clockwise we find that the angle between Angkor and temple of Solomon temple is 80 degrees with an accuracy in all -0.03.
Turn nonagon on 13 degrees clockwise. In this position we see that directions to Great Zimbabwe and Uluru are located symmetrically to azimuth of Mecca in 40 degrees.
