Formula: a² + b² = c². Where a and b are the legs and c is the hypotenuse (longest side). Enter any two values to find the third.

الأسئلة الشائعة

What is the Pythagorean theorem?
In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides: a² + b² = c².
What is a Pythagorean triple?
A set of three positive integers (a, b, c) that satisfy a² + b² = c². For example, (3, 4, 5) and (5, 12, 13).
Which side is the hypotenuse?
The hypotenuse is the longest side of a right triangle, opposite the right angle.
Can I find a leg if I know the hypotenuse and the other leg?
Yes. Rearrange the formula: a = √(c² − b²).
