What this tool is for
Right Triangle Calculator supports math checking in math calculators by showing how apply the formula shown on this page to the entered values. The page keeps the inputs, formula, and example together so the calculation can be checked before the number is reused.
When to use it
Use it when side a and side b are already known and you need a quick estimate before comparing options, checking a worksheet, or copying the result into another workflow.
Inputs
- Side A is one of the direct inputs used to calculate right triangle.
- Side B is one of the direct inputs used to calculate right triangle.
Formula
c = sqrt(a^2 + b^2)
Example
Sides 3 and 4 give hypotenuse 5.
What the result means
