Pythagorean Theorem

Formula

c = √(a² + b²)

For a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides.

Solving for a Side

  • c = √(a² + b²)
  • a = √(c² - b²)
  • b = √(c² - a²)

    • Exemple Résolu

    A right triangle with sides a=3 and b=4.

    1. c² = 3² + 4² = 9 + 16 = 25
    2. c = √25 = 5
    3. Area = 0.5 × 3 × 4 = 6
    4. Perimeter = 3 + 4 + 5 = 12
