Formula
Pythagorean theorem formula: a² + b² = c²
Where:
- a and b are the legs of the triangle
- c is the hypotenuse (longest side)
How to Use
Enter any two known side lengths in the input fields (leave the unknown field empty). Click "Calculate" to get the missing side value. The calculator automatically determines which side to compute. Ensure you enter positive numerical values only. Use "Clear" to reset all fields. Results display with complete calculation steps and decimal precision for accurate measurements in both academic and professional applications.
