Pythagorean Theorem Calculator
Calculate the length of a right triangle’s side using a² + b² = c²
What Is a Pythagorean Theorem Calculator?
A Pythagorean theorem calculator is a geometry tool that instantly solves for missing side lengths in right-angled triangles using the formula a² + b² = c², where c is the hypotenuse. Ideal for students, builders, and designers, it eliminates manual calculation errors while teaching this fundamental math principle.
Key Benefits
✅ Instant Solutions – Calculates any missing side (leg or hypotenuse) in seconds
✅ Step-by-Step Work – Shows the math behind each solution for better learning
✅ Handles Decimals & Fractions – Works with exact values or decimal approximations
✅ Real-World Applications – Useful for construction, navigation, and design projects
How It Works
- Enter 2 known sides (leave one field blank)
- Get the missing side with full calculation steps:
Example:
- Side a = 3
- Side b = 4
- Hypotenuse (c) = √(3² + 4²) = 5
Practical Uses
• Checking right angles in construction
• Calculating diagonal distances
• Solving physics/engineering problems
