Find the length of the hypotenuse (c) of a right triangle.
The Theorem
In a right-angled triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b).
Formula
a² + b² = c²
Geometry FAQs
Can I calculate a leg if I know the hypotenuse?
Yes. Algebraically, you can rearrange the formula to <strong>a² = c² - b²</strong>.
