Pythagorean Theorem Calculator
Calculate a right triangle's hypotenuse from its two perpendicular legs.
How to use
- Enter perpendicular leg a.
- Enter perpendicular leg b and calculate.
Capabilities and scope
The positive square root of the sum of squared legs gives the hypotenuse.
How it works
It uses c = √(a²+b²).
Example
a=3 and b=4 give c=5.
Useful for
- Find a diagonal from horizontal and vertical dimensions
- Verify right-triangle dimensions
Before you use it
- The formula assumes the two entered sides are perpendicular.
Frequently asked questions
Can it solve a missing leg from the hypotenuse?
The current input flow is specifically two legs to hypotenuse.
