Which of the following can be the sides of a righttriangle?(i) 2.5 cm,6.5 cm, 6 cm.(ii) 2 cm, 2 cm, 5 cm.(iii) 1.5 cm, 2cm, 2.5 cm.In the case of right-angled triangles, identify theright angles.

Explanation

To determine which of the given sets of sides can form a right triangle, we will use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

### Step-by-Step Solution:

1. **Evaluate the first set of sides: 2.5 cm, 6.5 cm, 6 cm.**
- Identify the longest side: 6.5 cm.
- Apply the Pythagorean theorem:
\[
