**Pythagorean Theorem**: The Oldest Mathematics Theorem

Pythagorean Theorem is the oldest mathematics theorem or development by the human, this theorem is combination thought of different branches of the mathematics like algebra, geometry. It is developed by Pythagoras in 500 BC but we get some evidence that Babylonians know about it in1800BC as we get a clay tablet known as Plimpton 322 , Which systematically lists a large number of integer pairs (a, c) for which there is an integer b satisfying.

a^{2} + b^{2} = c^{2}

Pythagorean Theorem or Pythagoras’ Theorem is a theory that states, that sum of two square’s areas whose sides are equal to the base (length b) and perpendicular (length a) of the right triangle is equal to the area of the square constructed on the hypotenuse (length c) of the right triangle. Where a,b and c are the side length of three squares.

So c^{2} = a^{2} + b^{2}

Theorem can be written as anÂ equation:

(hypotenuse)^{2} = (base)^{2} + (perpendicular)^{2}
