What is Pythagoras' theorem?

Did you know a famous math rule was secretly discovered over a thousand years before the guy it’s named after was even born? Grab a piece of paper and draw a triangle with one perfectly square corner. Now, imagine attaching a square to all three sides. If you cut up the two smaller squares, they will fit perfectly inside the biggest square—with absolutely no leftovers! This magical balancing act works for every single right-angled triangle in the universe. It is called Pythagoras’ theorem, named after a Greek thinker from 500 BCE. But there's a massive twist! Archaeologists found an ancient clay tablet called Plimpton 322 made by Babylonian scribes in 1800 BCE. That means they knew this secret code way before Pythagoras! From ancient builders stretching knotted ropes to make perfect pyramids, to the makers of your flat-screen TV and phone map apps today, this secret mathematical puzzle is hiding everywhere. Tune in to uncover the wild history of the world's most famous triangle!
