How this was worked out
- Step 1a² = c² − b² = 5² − 4²
- Step 2a = √9 = 3
Formula
a² + b² = c² → c = √(a² + b²)
Example
Input
a = 3, b = 4
Result
c = 5
Frequently asked questions
In a right-angled triangle, the square of the hypotenuse equals the sum of the squares of the other two sides: a² + b² = c².
Yes. Rearranged: a = √(c² − b²). Leave the side you want blank.
No — the theorem only applies to right-angled triangles.
