The sides of a triangle are 5 cm, 8 cm and 11 cm respectively. Demtermine whether it is a right angled triangle or not.

Explanation

To determine whether the triangle with sides 5 cm, 8 cm, and 11 cm is a right-angled triangle, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Here are the steps to solve the problem:

### Step 1: Identify the sides of the triangle
The sides of the triangle are given as:
- Side a = 5 cm
- Side b = 8 cm
