The Pythagorean theorem is a fundamental principle in geometry that relates the lengths of the sides of a right triangle. It states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This relationship can be expressed with the formula: c² = a² + b², where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.
Understanding the Pythagorean theorem is essential for various applications in mathematics, physics, engineering, and even everyday problem-solving. For instance, if you know the lengths of two sides of a right triangle, you can easily calculate the length of the hypotenuse using this theorem. This is particularly useful in construction, navigation, and computer graphics, where precise measurements are crucial.
To use the Pythagorean theorem calculator, simply input the lengths of sides A and B. The calculator will then compute the length of the hypotenuse for you. This tool is designed to simplify the process of finding the hypotenuse, making it accessible for students, professionals, and anyone interested in geometry.

Applications of the Pythagorean Theorem
The Pythagorean theorem has numerous applications in various fields:
- Architecture and Construction: Architects and builders use the theorem to ensure structures are built correctly and to calculate distances and angles.
- Navigation: In navigation, the theorem helps in determining the shortest path between two points, especially in air and sea travel.
- Computer Graphics: In computer graphics, the theorem is used to calculate distances between points in 2D and 3D space, which is essential for rendering images and animations.
- Physics: The theorem is applied in physics to solve problems involving vectors, forces, and motion.
Example Problem
To illustrate how the Pythagorean theorem works, consider a right triangle where Side A measures 3 units and Side B measures 4 units. To find the length of the hypotenuse (c), we can use the formula:
c² = a² + b²
Substituting the values:
c² = 3² + 4²
c² = 9 + 16
c² = 25
Taking the square root of both sides gives us:
c = √25 = 5
Thus, the length of the hypotenuse is 5 units.
