Pythagorean Theorem

🔹 What Is It?

In any right triangle, the square of the longest side (called the hypotenuse) is equal to the sum of the squares of the other two sides.

The formula is:
a² + b² = c²

🧩 Clue to Remember

It only works in right triangles.

🔹 Example

If one side is 3, and the other is 4:
3² + 4² = 9 + 16 = 25
So the hypotenuse is √25 = 5
