The Greeks may have documented and thoroughly understood what they were
doing in trig and geometry, but it seems the Egyptians knew very well the
right angle, 3-4-5 triangles, and true N-S ordinates very early on. From my
readings,IIRC the great pyramid sides deviate from N-S by some 2 seconds of
arc, which means their execution was as good as their design.

Geo-metry is derived from measuring-earth, I wonder what the greeks called
it themselves?
Al-gebra (break apart) was an Arabic invention, and they understood how it
worked.

So the Egyptians, predating Greek civilization, built the pyramids 
without understanding geometry or trigonometry? That is some serious 
random good luck.
