Understanding the Pythagorean Theorem

What is the Pythagorean Theorem?

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse equals the sum of squares of the other two sides. Key elements include:

  • Right Triangle - Triangle with one 90° angle
  • Hypotenuse - Longest side, opposite to right angle
  • Legs - Two sides forming the right angle
  • Formula: a² + b² = c²
  • Pythagorean Triples - Integer solutions
  • Converse - Triangle classification
  • Distance Formula - Coordinate application
  • Geometric Mean - Height relationships
  • Trigonometric Connections

Key Formulas and Relationships

Basic Formula:

c² = a² + b²

Finding Legs:

a = √(c² - b²)

b = √(c² - a²)

Finding Hypotenuse:

c = √(a² + b²)

Distance Formula:

d = √[(x₂-x₁)² + (y₂-y₁)²]
