    Step-by-step explanation:

    To figure out whether a triangle is a right triangle using only the side lengths, you can use the Pythagorean theorem:

    a^2 + b^2 = c^2

    1.5^2 + 2^2 = 3^2

    2.25 + 4 = 9

    Since this equation isn't true, these numbers cannot be the side lengths of a right triangle.
