The Pythagorean theorem is one of the most well-known principles in geometry. It provides a method for calculating the relationship between the sides of a right-angled triangle. Our Pythagorean Theorem Calculator makes this process simple, allowing you to quickly find the missing side of any right triangle. Whether you’re a student, teacher, or professional, this tool is perfect for all your triangle-related calculations.

What is the Pythagorean Theorem?

The Pythagorean theorem is a mathematical formula that relates the lengths of the sides of a right triangle. The theorem states that:

c² = a² + b²

Where:

is the length of the hypotenuse (the side opposite the right angle),
$a$ and $b$ are the lengths of the other two sides.

This formula is used to calculate the length of any side of a right-angled triangle when the lengths of the other two sides are known.

Frequently Asked Questions (FAQs)

1. What is the Pythagorean theorem used for?

The Pythagorean theorem is used to calculate the length of one side of a right-angled triangle when the lengths of the other two sides are known. It’s widely used in geometry, trigonometry, construction, and even navigation.

2. How does the Pythagorean Theorem Calculator work?

The calculator uses the Pythagorean theorem formula . You input any two sides of a right triangle, and the calculator automatically solves for the missing side.

3. Can I solve for the hypotenuse using this calculator?

Yes! If you know the lengths of the two legs $a$ and $b$ , you can calculate the hypotenuse $c$ by entering these values into the calculator.

4. What happens if I only know one side?

To use the Pythagorean Theorem Calculator, you need to input the lengths of two sides. If you only know one side, you will not be able to calculate the third side without more information.

5. Can I calculate non-right triangles using this tool?

No. The Pythagorean theorem only applies to right-angled triangles. This calculator is designed specifically for triangles with one 90-degree angle.

6. Is this calculator mobile-friendly?
