Pythagorean Theorem Calculator

How Does the Pythagorean Theorem Calculator Work?

The Pythagorean Theorem Calculator utilizes the fundamental principles of the Pythagorean Theorem to calculate the missing side of a right-angled triangle. The theorem states that in a right-angled triangle, 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.

The formula is expressed as: a² + b² = c², where `c` is the hypotenuse and `a` and `b` are the other two sides.

Practical Examples of Using the Pythagorean Theorem

For instance, if you know the lengths of two sides of a right-angled triangle, such as 3 and 4, you can calculate the hypotenuse as `√(3² + 4²) = 5`. Conversely, if you know the hypotenuse and one of the other sides, such as 5 and 3, you can calculate the missing side as `√(5² - 3²) = 4`.

Frequently Asked Questions About the Pythagorean Theorem

How do I calculate the hypotenuse of a right triangle?
Enter the lengths of the two other sides and use the formula `c = √(a² + b²)` to calculate the hypotenuse.

How can I calculate one of the other sides if the hypotenuse is known?
Enter the length of the hypotenuse and one of the sides, then use the formula `a = √(c² - b²)` to find the missing side.
