...favorably upon any jokes from the tutor. "Well, then, you may prove that the square described upon the hypotenuse of a right-angled triangle is equal to the sum of the squares described upon the other two sides, and also that the angles at the base of an isosceles...

...probably not responsible for what became known as Pythagoras' theorem, which states that the square on the hypotenuse of a right-angled triangle is equal to the sum of the squares on the other two sides. They did important early work in arithmetic, although they were...

...philosopher who lived in the sixth century BC Today, he is chiefly remembered for his mathematical theorem; the square of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two sides. Few people are aware that this same man is also considered the...

...nor thirty centuries, affect the clearness, or the charm, of Geometrical truth. Such a theorem as, "the square of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the sides" is as dazzlingly beautiful now as it was in the day when Pythagoras first...

...initial square, as implied by the theorem of Pythagoras, which says that the area of a square built on the hypotenuse of a right-angled triangle is equal to the sum of the squares on the other two sides. The diagonal plays here the role of a cause responsible for the...

...will instantly recognize it as a specific form standing for the Pythagorean theorem ('the square on the hypotenuse of a rightangled triangle is equal to the sum of the squares on the other two sides'), not as a combination of unrelated variables (letter signs). If...
