Question: In a triangle, if the lengths of the sides are 7 cm, 24 cm, and 25 cm, is it a right triangle?

Options:

1. Yes
2. No
3. Cannot be determined
4. Only if angles are known

Correct Answer: Yes

Solution:

To determine if it is a right triangle, we can use the Pythagorean theorem. Here, 25² = 7² + 24², which simplifies to 625 = 49 + 576, thus 625 = 625. Therefore, it is a right triangle.
