## Pythagorean Theorem Formula and how to use

Pythagorean Theorem Formula Using the Pythagorean Theorem formula for right triangles you can find the length of the third side if you know the length of any two other sides. Read below to see solution formulas derived from the Pythagorean Theorem formula:

**a**^{2}+b^{2}=c^{2}

## What is the proof of the Pythagorean Theorem ?

The proof of Pythagorean Theorem in mathematics is very important. In a right angle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. States that in a right triangle that, the square of a (a2) plus the square of b (b2) is equal to the square of c (c2).

## Pythagorean Theorem for Right Triangles

a = side leg a

b = side leg b

c = hypotenuse

A = area
