6 We know that : AA' = 232,805 m OA = 232,805 / 2 ≈ 116,403 m We are looking for SA: In the SOA triangle, according to the Pythagorean Theorem: SA² = OS² + OA² SA² ≈ 21965, , SA² ≈ 35515,26967 So, SA ≈ 188,455 m Then we have the ratio: SA / OA ≈ 188, 455 / 116, 503 ≈1, The golden ratio, supposed to appear in the middle of The Ancient Greece, was in fact, already present in the massive Egyptian Pyramid: The Pyramid of Cheops.
