Pythagorean Theorem Calculator

A simple online pythagoras theorem calculator to find the length of the hypotenuse side in a right angled triangle using the Pythagorean Theorem, which is also known as Pythagoras Theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides (adjacent and opposite). Using this online Pythagorean theorem calculator, you can find hypotenuse, adjacent side and opposite side alternatively with the other known values.

Formula:

Pythagoras Theorem Triangle c 2 = a 2 + b 2 Where, a = Adjacent side (a) b = Opposite side (b) c = Hypotenuse side (c) of the right angled triangle.

Example:

Find the hypotenuse of a triangle with adjacent and opposite side as 5 and 8 cm.

Pythagoras Theorem,

c 2 = a 2 + b 2
Hypotenuse = √(52 + 82)
= √(25 + 64)
= √(89)
= 9.43 cm

The Pythagorean Theorem was one of the earliest theorems known to ancient civilizations. This famous formula is named for the Greek mathematician and philosopher, Pythagoras.
