Understanding the Pythagorean Theorem

The Formula:
a² + b² = c²

Where:
a and b are the lengths of the two legs (shorter sides)
c is the length of the hypotenuse (longest side, opposite the right angle)

History

The Pythagorean theorem is named after the ancient Greek mathematician Pythagoras (c. 570–495 BC), although evidence suggests that Babylonian mathematicians understood this relationship over 1,000 years earlier.

Common Pythagorean Triples

  • (3, 4, 5): 3² + 4² = 9 + 16 = 25 = 5²
  • (5, 12, 13): 5² + 12² = 25 + 144 = 169 = 13²
  • (8, 15, 17): 8² + 15² = 64 + 225 = 289 = 17²
  • (7, 24, 25): 7² + 24² = 49 + 576 = 625 = 25²

Real-World Applications

  • Construction: Ensuring corners are square (90°)
  • Navigation: Calculating shortest distance between two points
  • Architecture: Designing roofs, ramps, and stairs
  • Physics: Resolving vectors into components
  • Computer Graphics: Calculating distances in 2D and 3D space
