Determine whether the triangle whose lengths of sides are 3 cm, 4 cm,5 cm is a right-angled triangle.

Explanation

To determine whether the triangle with side lengths of 3 cm, 4 cm, and 5 cm is a right-angled triangle, we will use the Pythagorean theorem. The 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.

### Step-by-Step Solution:

1. **Identify the sides of the triangle**:
- The sides are given as 3 cm, 4 cm, and 5 cm.
- We will identify the longest side, which is the hypotenuse. Here, the hypotenuse is 5 cm.
