The twelve to one ratio gives the following dimensions:
Pyramid height                  479.94
Pyramid slant height         610.9226   Angle 51º 46' 34"
Pyramid base length         756
Pyramid base half length  378

When the above dimensions have been put in place the most important measurement is 55.6898 the entrance
height from the base, the KEY to all dimensions. It also builds all interior horizontal and vertical ratios.
All interior dimensions are multiples of 55.6898

Queen's Chamber floor height from the pyramid base is 1.25 X 55.6898. (1.25 X the Entrance height from the base)
King's' Chamber floor height from the pyramid base is 2.5 X 55.6898. (2.5 X the Entrance height from the base)
The King's Chamber floor height from the base is twice the Queen's Chamber floor height from the base.
Insert the Descending Passage.
Insert the Ascending Passage.
Note the Descending and Ascending angles,26. 565. This is the original design not necessarily what was
accomplished. Time, 4500 years, also has to be factored in. There is a mistake in construction in the ascending
passage that changes the angle to today's measurements. Follow the design measurements and question why the
floor meets the bottom of the Great Step. It becomes quite obvious.
Showing ratios using 55.6898, they are the most important ratios. The dimension 55.6898, (the Entrance height
from the base is shown in red. It is the most important dimension in the Great Pyramid of Giza.
Multiples of 55.6898, the Entrance height from the base The ratios are evident, e.g. 2.5 is 2.5 X 55.6898 = 139.2245.
Three reference points were selected. The Entrance height from the base, The Queen's Chamber floor height from
the base and the King's floor height from the base.

The comparisons between the ancient measurements verified by archaeologists and the design using the 12:1 ratio
are extremely close. The 12:1 design shows how 'it was meant to be'.

It would be almost impossible to construct such an enormous object and keep all the dimensions exactly as it was
designed.

Showing the 12:1 ratio and the resultant dimensions created. This ratio is the root of all dimensions in the Great
Pyramid of Giza and gives the height, slant height and entrance height values.

Without these values other dimensions cannot be calculated.
Note:
The 12:1 ratio is acceptable mathematics for the time the Pyramid was built.
The ancient Egyptians would have used this ratio.
 The Great Pyramid of Giza
Entrance Height 55.6898
The difference between the actual measurements and the
measurements in this design. The reference points are extremely
close.
The King's Chamber difference is       1.642
The Queen's Chamber difference is    0.0473
The Entrance difference is                   0.0065
This accuracy proves that this design follows the design used by the Egyptians. The mathematical
descriptions are different of course but the end result is the same. We describe the Entrance
height as 55.6898. How did the Egyptians describe it. Was it cubits or something else, it would be
nice to know. One thing is certain, this measurement was very important to The Pharaoh and his
designers and builders.
 RATIOS Built The Great Pyramid
The geometrical layout of the Great Pyramid interior was accomplished by manipulating ratios.
Two lengths were used:

1)    Derived from the Entrance height from the Pyramid Base.                                      55.6898
This ratio was used on horizontal and vertical planes only.

2)    Derived from the Descending passage from the Entrance to the Pyramid Base.   124.5262
This ratio was used on angular planes only.

Both ratios were connected. The start and end of the vertical meets the start and end of the
horizontal.
Precisely!

e.g.   The Ascending passage angular ratio meets the Base to King's Chamber vertical ratio.
Precisely!

This means that the Passageway angles are controlled by the ratio values and establishes the
original desired Passageway angles at 26.565º and 26.565º respectively,

Their is no reason to today to question what the angles were meant to be.
Angular ratios derived from the Entrance to the base 124.5262
Vertical and horizontal ratios derived from the Entrance height from the base 55.6898
The end of the ratio section
There is secrecy in the dimensions. The Entrance height is used in almost every dimension. Why? What is 55.6898? Other
than being a part of the 12:1 ratio what does it mean?

Did the ancients use multiples of 1.618 and 8.618?

These dimensions require investigation above all else.

And the Pharaoh said "Keep it simple". And It was. And it was done.
