Free Pythagorean Theorem Calculator (Find Hypotenuse & Sides) Online
Solve right-angled triangle sides using a² + b² = c². Computes missing hypotenuse c or leg a/b with exact radical roots and angle degrees. — 100% free online utility, zero sign-up, zero paywalls, and private client-side processing.
How It Works
Select Missing Side
Choose to solve for Hypotenuse (c) or Leg (a or b).
Enter Known Lengths
Input positive lengths for the two known triangle sides.
Evaluate Theorem
Computes c = √(a² + b²) or a = √(c² - b²).
Review Area & Angles
Inspect calculated triangle area, perimeter, and interior angles.
