The correct answer for this item is this one: " The triangle is a right triangle because 25 + 144 = 169

Given the side lengths 5 cm, 13 cm, and 12 cm, we can confirm it if it is a right triangle by applying the pythagorean theorem.

13^2 = 12^2 + 5^2

169 = 144 + 25

169 = 169

So this confirms that it is a right triangle.
