Answer:A right triangle with side lengths 3 cm, 4 cm, and 5 cm is a classic example of a Pythagorean triple. - The sides 3 cm and 4 cm are the legs (perpendicular sides).- The side 5 cm is the hypotenuse (longest side opposite the right angle). You can check it using the Pythagorean theorem:3^2 + 4^2 = 9 + 16 = 25, and 5^2 = 25, so it satisfies the condition a^2 + b^2 = c^2.
