To determine if the sides 5, 8, and 9 form a right triangle, we can use the Pythagorean theorem, which 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. Here, 9 is the longest side. Calculating: (5^2 + 8^2 = 25 + 64 = 89) and (9^2 = 81). Since (89 \neq 81), the sides 5, 8, and 9 do not form a right triangle.
