- The definition of the Pythagorean Theorem is a mathmatical relationship of the lengths of the sides in a right triangle - if you square the length of the two shorter sides and add them together, that will equal the length of the longest side squared.
An example of the Pythagorean Theorem is a 3 x 4 x 5 triangle - 3 squared is 9, 4 squared is 16, and 5 squared is 25. 9 plus 16 equals 25.

The Pythagorean theorem is: a2 + b2=c2
Pythagorean theorem - Cultural Definition
The theorem in geometry that, in a triangle with one right angle, usually called a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
- The theorem is often expressed a2 + b2 = c2.
- 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 32 + 42 = 52; that is, 9 + 16 = 25.
