# Pythagorean Theorem

In mathematics, the Pythagorean theorem, also known as **Pythagoras' theorem**, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

` ````
public static double Hypotenuse(double side1, double side2)
{
return Math.Sqrt((side1 * side1) + (side2 * side2));
}
```

### Example

` ``double result = Hypotenuse(8, 3);`

### Output

` ``result: 8.54400374531753`
