Formula
a² + b² = c²
For a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides.
Example
If the legs are 3 and 4 units, the hypotenuse is 5 units because 3² + 4² = 25.
Frequently Asked Questions
What is a right triangle?
A right triangle has one angle equal to 90° and the opposite side is the hypotenuse.
How do I know the area?
Use Area = (base × height) / 2.
Can I get the angles?
Yes. Using sine, cosine, or tangent, the remaining acute angles can be found from the side ratio.
