Understanding the Pythagorean Theorem

The Basic Formula

  • a² + b² = c²
  • c is the hypotenuse (longest side)
  • a and b are the legs (shorter sides)
  • The theorem only works for right triangles

Common Applications

  • Construction and architecture
  • Navigation and surveying
  • Engineering and design
  • Distance calculations

Tips

  • Units must be consistent
  • All sides must be positive
  • The hypotenuse is always the longest side
  • Double-check your measurements
