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.
- (geometry) A mathematical theorem which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of those of the two other sides.
- The Pythagorean theorem only applies to right triangles.
- (functional analysis) A generalization of the Pythagorean theorem for Euclidean triangles to Hilbert spaces
Named after Pythagoras, from Ancient Greek Î Ï…Î¸Î±Î³ÏŒÏÎ±Ï‚ (Pythagoras), Greek mathematician and philosopher who by tradition is credited with theorem's discovery and proof.
