Pythagoras Theorem

Pythagoras, the famous Greek philosopher, was born in about 580 B.C. in Samos, Ionia, and died in about b20 B.C. in Metapontum, Lucania. He gave a wonderful relation between the lengths of the sides of a right triangle which is generally known as the Pythagorean Theorem.

Although this theorem was known to the Babylonians 1000 years earlier. But, Pythagoras is believed to have been the first to discover a proof of this theorem. And, for this reason, the
theorem bears his name.

Theorem Statement

In a right triangle, the square of the hypotenuse equals the sum of the squares of its remaining two sides.

Pythagorean Theorem Formula

Thus, if Δ ABC is a right triangle right angled at C, so that AB is the hypotenuse and, AC and BC are the sides of the tight angle, then

Formula

(AB)2 = (BC)2 + (CA)2
(Hypotenuse)2 = (Leg (a))2 + (Leg (b))2
c2 = a2 + b2 where a = BC, b – CA and c = AB.

How to use Pythagorean Theorem Calculator?

You can see, there are three calculators at the top of the page. The first one is to calculate Hypotenuse (c) and second and third is to calculate Leg (a) and Leg (b). So, just follow the instruction below.

  • Firstly, Open the Pythagorean Theorem Calculator.
  • To calculate Hypotenuse (c), just enter the Leg (a) and Leg (b) values.
  • As a result, you can find the Hypotenuse (c) result in third input box.
  • Similarly, you can find Leg (a) and Leg (b) values very easy and quickly.

Above all process shows the Pythagorean Theorem calculation.
