Pythagoras was a Greek mathematician and philosopher who lived in the 6th century BC and is best remembered for the Pythagorean theorem (the square of the hypotenuse of a right triangle is equal to the sum of the squares of the opposite two sides).
Euclid was a Greek mathematician living in the 4th century BC who taught at the university in Alexandria, Egypt. He became known as the Father of Geometry many years after publishing a thirteen volume work called Euclid's Elements in which he compiled and explained all the known mathematics of his time. Euclid's Elements is the world's most famous mathematical work and is also the oldest continuously used mathematical textbook. It is the foundation of the geometry still being taught in schools almost two and one-half millennium after Euclid's death."
