Right Triangle (Pythagorean) Calculator
Solve a right triangle: enter any two sides and get the third side plus both acute angles.
How it works
a^2 + b^2 = c^2. Enter any two sides; the third side and both acute angles are solved.
Worked example
a = 3, b = 4: c = sqrt(9 + 16) = 5, with a 36.87-degree angle at side a.
When to use it
- Sides a and b are the legs; c is the hypotenuse (longest side).
- The 3-4-5 triangle is the classic way to square a corner.
