what is Pythagorean Theorem? 8==================================================)

In mathematics, the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Yes, you can use google, if you want.

My definition:

The Pythagorean Theorem, also called Pythagoras's Theorem or Pythagoras Theorem, is the relations of lengths of the 3 sides of a right triangle. It says that the sum of the square of the lengths of the 2 legs is equal to the square of the hypotenuse.
