One of our users asked why we do not have a calculator on the Pythagorean theorem.
Indeed, we've already had plenty of calculators about triangles but none about the right triangle. Well, maybe because of its simplicity. If someone is lazy to calculate - here it is. As usual, some theory can be found below the calculator
The Pythagorean theorem, 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.
If we denote hypotenuse as c and two legs as a and b, we can write the following equation, often called the Pythagorean equation:
From this, we can quickly get the formulas for the unknown value.
In the calculator above, if you select the "two legs" option, then you are solving for the hypotenuse (c), and the hypotenuse is
If you select the "leg and hypotenuse" option, then you are solving the remained leg, and if it is a, then it equals to
If it is b, then it equals to
P.S. Wikipedia says there are 367 ways to prove the Pythagorean theorem.
