Golden Ratio – Phi



A straight line is said to have been cut in extreme and mean ratio when, as the whole line is to the greater segment, so is the greater to the less. [Euclid]

The extreme and mean ratio is also known as the golden ratio, or Phi. If the smaller part = 1, and larger part = G, the golden ratio requires that  G is equal approximately 1.6180

Does the Great Pyramid contain the Golden Ratio?

Assuming that the height of the GP = 146.515 m, and base = 230.363 m, and using simple math we find that half of the base is 115.182 m and the “slant height”  is 186.369 m

Dividing the “slant height” (186.369m) by “half base” (115.182m) gives = 1.6180, which is practically equal to the golden ration!
