Pythagorean theorem - Wikipedia
 
When Euclidean space is represented by a Cartesian coordinate system in analytic geometry, Euclidean distance satisfies the Pythagorean relation: the squared distance between two points equals the sum of squares of the difference in each coordinate between the points. 
  
Pythagorean Theorem Calculator
 
This calculator solves the Pythagorean Theorem equation for sides a or b, or the hypotenuse c. The hypotenuse is the side of the triangle opposite the right angle. For right triangles only, enter any two values to find the third. See the solution with steps using the Pythagorean Theorem formula. 
  
Pythagorean Theorem - Math is Fun
 
When a triangle has a right angle (90°) ... ... and squares are made on each of the three sides, ... ... then the biggest square has the exact same area as the other two squares put together! (press Go). It is the "Pythagorean Theorem" and can be written in one short equation: Note:

Pythagoreanism - Wikipedia
 
Pythagorean philosophers believed that there was a close relationship between numbers and geometrical forms. Early-Pythagorean philosophers proved simple geometrical theorems, including "the sum of the angles of a triangle equals two right angles". 
  
Pythagorean Theorem - Math.net
 
The Pythagorean Theorem shows the relationship between the sides of a right triangle. It states that for a right triangle, the sum of the areas of the squares formed by the legs of the triangle equals the area of the square formed by the triangle's hypotenuse.
