I can expand on 9. Gravity goes in a constant linear direction for all intents and purposes. This allows for easy creation of right angles. Once you’ve got an L, string, and a small weight you can start doing some real cool shit if you dedicate your entire life to carving brick and stone.
For right angles in particular, the Egyptians have known for millennia that stretching out a circular rope of 12 cubits into a 3-4-5 triangle will produce a right angle.
