Frequently Asked Questions
Does this work for any triangle?
No, it assumes a right angle between the two legs you enter (a and b).
How is the area calculated?
As half the product of the two legs, since they form the base and height of the right triangle.
What inputs does the Right Triangle Calculator need?
You'll need to provide: Side A, Side B. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Right Triangle Calculator?
The Right Triangle Calculator applies the formula exactly as calculated — Hypotenuse (Pythagorean theorem) = √(a² + b²). Area = ½ × a × b. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Right Triangle Calculator free to use?
Yes, the Right Triangle Calculator is completely free, requires no signup, and runs instantly in your browser.
