Frequently Asked Questions
A right triangle is a triangle that has exactly one angle measuring 90 degrees.
No, you need at least two pieces of information (two sides, or one side and one angle] to solve the triangle.
It is the formula a² + b² = c², where c is the hypotenuse and a, b are the other two sides.
For the hypotenuse result, no. They are interchangeable as the two "legs" of the triangle.
The angles in this tool are provided in degrees for standard geometric use.
