    Answer:

    It is an acute triangle

    Step-by-step explanation:

    If it is an acute triangle, a^2 + b^2 > c^2

    If it is a right triangle, a^2 + b^2 = c^2

    If it is an obtuse triangle, a^2 + b^2 < c^2

    If it is an equilateral triangle, a = b = c

    6^2 +8^2  ?  9^2

    36+64 ? 81

    100 ? 81

    ? is >, meaning it is an acute triangle.
