Pythagorean Theorem Calculator

Calculate missing side of right triangle using a² + b² = c²

📐 Pythagorean Theorem Calculator

Calculate missing side of right triangle: a² + b² = c²

📌 Pythagorean Theorem

a² + b² = c²
  • • a, b = legs of right triangle
  • • c = hypotenuse (longest side)
  • • Works only for right triangles (90° angle)

Solution

Hypotenuse (c)
5.0000

Step-by-Step

1. Formula: c² = a² + b²
2. Substitute: c² = 3² + 4²
3. Calculate: c² = 9 + 16 = 25
4. Take square root: c = √25 = 5.0000

Triangle Properties

Side a

Hypotenuse
5.00

📐 Finding Hypotenuse

c = √(a² + b²)

When you know both legs (a and b), use this formula to find the hypotenuse.

📏 Finding a Leg

a = √(c² - b²)

When you know one leg and hypotenuse, use this formula to find the other leg.
