Yes, indeed -- a very important point!
I emphasized Pythagoras, because I include a submodule on Pythagoras and "his" "3, 4, 5 triangle" in my unit on "Archaeology for Fourth Grade"... (Even today's archaeologists use the principle for laying out precisely square excavation grids...)
But, then I "blow the Greek out of the water" by showing that Amenhotep in Egypt beat Pythagoras to it by over a millennium -- when he used the same "triangle" for laying out the Pyramids... '-)
“Amenhotep” or Imenhotep, the medicine guy (the mummy)?
