Understanding the Pythagorean Theorem
The Pythagorean theorem states that in a right triangle:
- a² + b² = c²
- where c is the hypotenuse (longest side)
- and a and b are the other two sides (legs)
Properties
- Only works for right triangles (90-degree angle)
- The hypotenuse is always the longest side
- All sides must be positive numbers
- The theorem works in both directions
