> the meter was defined four millennia after the pyramid was built. Not only this, but also the sexagesimal degree divided into minutes, as a unit for angle measurement, was defined a couple of millennia later after the pyramid was built. Decimal fractions of sexagesimal degrees were not used before the last few centuries.
