Pythagorean theorem
[ pĭ-thăg′ə-rē′ən ]
A theorem stating that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other sides. It is mathematically stated as c2 = a2 + b2, where c is the length of the hypotenuse and a and b the lengths of the other two sides.

notes for Pythagorean theorem
The simplest whole number expression of this theorem is called the 3, 4, 5 triangle. In a right triangle, if one side measures three units, and the second side measures four units, the hypotenuse must measure five units because 3
2 + 4
2 = 5
2; that is, 9 + 16 = 25.
