The MagneticTiles were originally developed in Japan, where they were sold under the name Pythagoras.
Pythagoras of Samos (c. 570 – c. 495 BC) was an ancient Ionian Greek philosopher and the eponymous founder of Pythagoreanism.
The Pythagorean theorem:
When a triangle has a right angle (90°) and squares are made on each of the three sides, then the biggest square has the exact same area as the other two squares put together!
The longest side of the triangle is called the "hypotenuse".
