Teotihuacan
Northsouth axis of whole site of Teotihuacan divided by distance between the centers of the Sun and Moon pyramids (2,400 meters / 800 meters) = 3.
The spacing of the city's streets,
fiftyseven (57) meters divided by 3 = 19.

19 and the pentagon
The number nineteen also plays a unique role in the measure of the pentagon... the diagonal of the pentagon has the remarkable property of being the geometric mean between the diameters of the circumscribing circle and the height of the pentagon.
These numerical relationships which approach those of the Pharaonic canon of 18 and 19, are as follows:
The number 19 is significant to the Baha'i, whose calendar is 19 months of 19 days each.
The Bahai also attribute significance to the number 95, which is 19 x 5. Coincidentally, the EarthStar western North America map actually has 95 points; the 19 'main' points, the points of the 19 triangles, the 19 'halfway' points on the inner ring, and the 38 points on the middle ring.

19.5 degrees is the angle that's been found by researchers (Richard C. Hoagland, Stanley McDaniel, Erol Torun, Horace W. Crater, etc.) to be repeatedly encoded in the structures of Cydonia (see Mars).
It is viewed as a definite 'signal in the noise'  some kind of a 'message' left there by some intelligence. 19.5 is called t, the 'tetrahedral constant', because of its significance in tetrahedral geometry (a tetrahedron is a pyramid shape composed of four equilateral triangular sides): the apexes of a tetrahedron when placed within a circumscribing sphere, one of the tetrahedron's apexes touching the north pole, the other three apexes touch the surface of the sphere at 19.5 degrees south latitude.
Why this number would be important to the builders of the Martian structures is not clear (though Hoagland is theorizing that it has to do with what he calls "hyperdimensional physics").
The emphasis on 19.5 degrees is not confined to the Martian structures.
It has been found to be associated with various ancient structures here on earth, like Giza pyramids, Avebury (the largest stone circle in the world, near Stonehenge), Pyramids of the Sun and Moon at Teotihuacan, etc.
It is also worth noting that the Egyptian hieroglyph for Sirius, the brightest star in the sky which was extremely important to ancient Egyptians, is an equilateral triangle which can be viewed as a 2dimensional representation of a tetrahedron; and in the Egyptian translation, it means a doorway... a sort of 'stargate'.
Curiously, it has also been observed that 19.5 degrees is closely linked, for some reason, with the NASA space missions (for example, Mars Pathfinder landed at 19.5 degrees lat. of Mars on July 4, '97). In fact, not only did Pathfinder landed at 19.5 N, the longitude of the landing site was approximately 33 W  which is the very number of the longitude of the apex of the Great Bend of the Nile (33 E)!.
Now, this strongly insists on the relevance of the Nile numbers, and someone behind the scenes is well aware of it. As we move on, the number, 19.5, will also be very important in my Nile Timemap theory.
Perhaps, as the NileMars connection bridged by '19.5' appears to suggest, Mars was somehow involved during the 'Prometheus / Pandora period'.
