TIUNAKO. NONAGON. Orient one nonagon to the cardinal points and the other one turn on 10 * in any direction. Thus, we divide the circumference by 10 *.
This position clearly shows that azimuths of Teotihuacan, Stonehenge, Baalbek and Samaipata distributed around Tiwanaku multiply to 10 *, with small errors.
Azimuths of Nazca desert and Por Bajin, which as we know are perpendicular to each other, as well to azimuth of Uluru, divide 10*in half. It is easy to calculate yourself errors in each concrete case as the end of the exact value of azimuth should be 0.00 * or 5.00 * for Uluru, Nazca and Por Bajin.
It is noteworthy that Samaipata, located relatively close to Tiwanaku (5 * along the arc of globe), has azimut’s error only 0,03. Moreover, Samaipata, as we shall see later, also has an orientation to Tiwanaku, only in accordance with pentagram. See article "SAMAIPATA.PENTAGRAM. "Thus, Tiwanaku and Samaipata are two clearly interrelated objects.
In the article "LOCATION OF ANCIETN STRUCTURES IN THE GOLDEN SECTION.", we told about the fact that Teotihuacan and Tiwanaku are equidistant with accuracy 0.1 * from Baalbek in the golden section. In this combination, we see that azimuths of Teotihuacan and Baalbek divide half of circumference in the ratio of 80/100 *, with accuracy 0.2. In this case from the direction to the north to azimuth of Teotihuacan are 40 *, with the error of 0.45 * and to the directions to Baalbek are 60 *, with the error of 0.69 *.

Having turned nonagon on 3 * clockwise, we find that azimuths of more 4 objects Great Pyramid (GP), Mecca, Lalibela and Sigiriya located multiply to10 * relatively to each other. The difference between azimuths of GP and Mecca is 10.34 *, the error is + 0.34 *. Between azimuths of GP and Lalibela –are 20.07 *, the error is + 0.07 *. Between azimuths of GP and Sigiriya are 39.46 *, the error is 0.54 *.

In another article "MYSTERIES OF SAINT PETERSBURG. LOCATION OF CITY "it was a question that Tiwanaku is equidistant from GP and the North Pole, forming an equilateral triangle whose base is the meridian of GP, and height is the line Tiwanaku  St. Petersburg. Turning nonagon about on 11 * clockwise we find that the angle between the line of Tiwanaku  St. Petersburg and the direction to Lhasa is close to 20 *, with the error of 0.37 *.
There is another interesting moment related with the objects of this combination, which confirms again once more its nonrandomness. The fact is that St.Petersburg lies on the meridian of GP and the angular distance between them is  30 *. Between the meridians of GP and Lhasa are 60 *, and the angle between these objects in Tiwanaku is 20 *.
Besides, the distance from Tiwanaku to St. Petersburg is 12084 km or 108.5 * along the arc of globe. Therefore, Tiwanaku and St. Petersburg divide their large circle in the ratio of pentagram. See. Article "PENTAGRAM. LOCATION OF KEY POINTS OF SDMS."
Summing up small result of expound above, we can say that Tiwanaku fully corresponds to its name "The central stone" which is a reference of important point in the system of ancient monumental buildings (SDMS).
