Explore PythagoreanTheorem on MathWorld


The Pythagorean theorem is an equation relating the lengths of the sides of a right triangle as a squared plus b squared equals c squared, where c is the length of the hypotenuse.

Pythagorean theorem is a middle school-level concept. It is listed in the California State Standards for Grade 7.

Prerequisites

Hypotenuse: The hypotenuse is the longest side of of a right triangle, which is always opposite the right angle.
Right Triangle: A right triangle is a triangle that has a right angle. The Pythagorean Theorem is a relationship among the sides of a right triangle.
Trigonometry: Trigonometry is the study of angles and of the angular relationships of planar and three-dimensional figures.
