Pythagorean Theorem
In a right-angled triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b).
c² = a² + b²
Example 1 (3-4-5 Triangle)
Side a = 3, Side b = 4
- c² = 3² + 4² = 9 + 16 = 25
- c = √25 = 5
Example 2
Side a = 6, Side b = 8
- c² = 6² + 8² = 36 + 64 = 100
- c = √100 = 10
How to Use
- Enter the lengths of the two shorter sides.
