If I lack detailed knowledge of the old Kingdom KMT then you lack knowledge of physical and mathematical prinicples.
I make no secret of the fact that my acuity with mathematics is sadly lacking. The case is not so bleak with physical principles because I have spent years carefully studying engineering principles of the Early Bronze Age to try to understand their building techniques. Based on what you've written to date, I don't think you have.

An engineers square that they acquired from the local hardware store? How did they have that knowledge? Where did their knowledge for example of the perfect right angle come from and their means to check it? Think about it.
The right angled triangle did not supposedly come for another 2000 years - Mr Pythagoras.
No protractors, no engineering surfaces, milling machines, precision tooling, just plain old string and diorite hammers (LOL).
Think again. No, they did not possess advanced building or engineering tools, but such tools weren't necessary to construct their monuments. They did indeed have right-angle squares, despite what Mr Pythagoras says (and Pythagoras would've had no meaningful knowledge of Old Kingdom Egyptian engineering in the first place). Though no actual-size square has yet been found, quite a few in reduced, amuletic form are known. An example can be seen at right-center in
this photograph. The detail isn't clear but many of these amuletic squares even have the little rules on them to indicate measurement.
Establishing right angle does not require modern, advanced methods. The Egyptians may have also used set squares, the Pythagorean triangle (don't let the name fool you--it's a lot older than he is), and intersecting arcs. Instead of simply dismissing the wealth of evidence that's out there, at your disposal to read and research, try looking into it first. Have you ever studied the numerous Egyptian mathematical papyri that have been excavated through the years? Most of them date to later than the Old Kingdom, but they detail the principles and formulae required to build any of their monuments, including pyramids. Also, at least
consider looking into the two books I recommended earlier. Much of what you're saying is impossible is covered in at least some way in just those two books. I've handed you the resources to get started, so please get started and stop summarily dismissing evidence.

Oh and by the way - Mr Petrie states that they used jewelled copper saws. How does he speculate that these were made and were are they now - there must have been thousands needed!
Mr. Petrie would be wrong, then. To be frank I've never read that statement in the letters and biographies I have of Flinders Petrie, but he was wrong about a number of things. Then again, that's not surprising. I don't think you really understand, zoser, how much we have learned since the early days of Petrie. Petrie himself would be shocked to see how much knowledge we've gained since his day, and how much science has advanced. He'd probably be pretty miffed, too, to know that some of his ideas have been overturned.
In other words, zoser, turn to more current sources. You're limiting yourself. Also be aware that Petrie surveyed at Giza but never actually excavated at the Great Pyramid itself. His understanding of that monument was consequently limited. If you want to benefit from Petrie's long excavation experience, turn to his sites such as in the Delta, Fayoum, or in Abydos. Use sources that are relevant to the archaeology of a site.
