Unlock the power of the Pythagorean theorem with our easy-to-use Missing Side of a Right Triangle Calculator. Whether you need to find the hypotenuse or a specific leg (side a or side b), simply input two known sides, and let our tool do the math instantly. Perfect for students, engineers, and DIY enthusiasts.
Formula:
The calculator employs the fundamental Pythagorean theorem to determine the length of the unknown side in a right-angled triangle. It can find a leg or the hypotenuse:
- To find the Hypotenuse (c): c = √(a2 + b2)
- To find Leg A (a): a = √(c2 - b2)
- To find Leg B (b): b = √(c2 - a2)
Where:
- a = Length of Leg A (one of the shorter sides adjacent to the right angle)
- b = Length of Leg B (the other shorter side adjacent to the right angle)
- c = Length of the Hypotenuse (the longest side, opposite the right angle)
