Secrets of the Pyramids and the Sphinx
Whoever built these structures, possessed advanced mathematics, engineering and building techniques. Even with our modern equipment, we could not duplicate these enigmatic monuments.
With its base angles at 51 degrees 51 minutes. If you bisect this triangle and assign a value of 1 to each base, then the hypotenuse (the side opposite the right angle) equals phi (1.618..) and the perpendicular side equals the square root of phi. A circle is drawn with it's center and diameter the same as the base of the large triangle. This represents the circumference of the earth. A square is then drawn to touch the outside of the earth circle. A second circle is then drawn around the first one, with its circumference equal to the perimeter of the square. (The squaring of the circle.) This new circle will actually pass exactly through the apex of the pyramid.
A circle drawn with its center at the apex of the pyramid and its radius just long enough to touch the earth circle, will have the circumference of the moon.
