Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm is a right triangle?

The hypotenuse in a right triangle is the longest side.to explain whether a triangle is a right triangle, we have to apply pythagoras: 13² = 12² + 5²169 = 144 + 25169 = 169, then this triangle is a right triangle

Perform the pythagorean theorem on it.5^2 + 12^2 = 13^225 + 144 = 169169=169therefore it satisfies the theorem and is a right triangle.
