Guide to the Pythagorean Theorem
The Formula
a² + b² = c²
where:
- a and b are the lengths of the two legs (the sides adjacent to the right angle)
- c is the length of the hypotenuse (the longest side, opposite to the right angle)

Frequently Asked Questions
What is the Pythagorean theorem?
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) equals the sum of squares of the other two sides (a and b). It's written as: a² + b² = c².
What is a right triangle?
A right triangle is a triangle that has one 90-degree angle (right angle). The side opposite to the right angle is called the hypotenuse and is always the longest side.
How accurate are the calculations?
Our calculator provides results rounded to 4 decimal places, which is sufficient for most practical applications. The internal calculations are performed with full floating-point precision.
Why isn't my triangle forming?
Remember that the hypotenuse must always be longer than either of the other two sides. If your inputs don't satisfy this condition, they cannot form a right triangle.
Can I use this for real-world measurements?
Yes! This calculator is perfect for practical applications in construction, engineering, architecture, and DIY projects where right angles are involved.
