Pythagorean Theorem Calculator is an online tool used to calculate the third side of the right angled triangle by the other two known side values. Pythagorean Theorem is a Trigonometric function defined as the sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c)
The theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation
a2 + b2 = c2
A key to the distance formula, the theorem is implicitly present in all scientific models and engineering computations involving spatial relationships or trigonometry.
