**To build the pyramid of Cheope the Egyptians have applied the golden ratio?**

The students of two classes of the institute "Veronese" have made a study to answer to this question considering that Euclide will formalize his "extreme proportion and average" about two thousand years later.

From the activity of 39 students has emerged that a number next to φ = 1618033… is present in the proportions of the great pyramid.

Here you can see the pictures made by four students that exemplify better the work:

CH:HB=1,616

AB:CO=1,575

**At the end of the work the students have established that:
the ancient Egyptians didn't know the φ = 1618033… but they looked for a harmonic proportion that, as a consequence, was next to the, "golden number."**

However not all the students agree and a minority (7 on 35) believes that the found relationships are only casual. And 3 students on 35 think the Egyptians knew and applied the golden ratio.

**Fresco from Thutmosis' tomb**

the navel (belly button) represents the mean of the golden ratio:

The nevel is positioned such that the ratio of the short half to the long half is equal to the ratio of the long half to the whole.

From feet to navel= 1

From feet to head= 1,618

In this case the ratio is 1,580665 (close to 1,618)
