Quickly determine if a triangle with given side lengths is a right-angled triangle. Our easy-to-use tool applies the Pythagorean theorem (a² + b² = c²) to verify if your triangle forms a perfect 90-degree angle. Ideal for geometry, carpentry, or any task requiring precise right angles.
Formula:
The calculator determines if a triangle is right-angled using the Pythagorean Theorem:
a2 + b2 = c2
Where:
- a = Length of the first leg
- b = Length of the second leg
- c = Length of the hypotenuse (the longest side)
If the sum of the squares of the two shorter sides equals the square of the longest side, the triangle is a right triangle.
