Uh, they did. But right angles pre-dated the pyramids by at least several
decades.

Right angles (and every other angle) have been around forever, it's just
that nobody named them. Same as gravity, space, oxygen, grass, ocean, sky,
etc. etc.

The circle is even older.

See above. There has been at least two circles from the day man was 'born',
and he saw them every day, the sun and the moon
