    Answer:

    No

    Step-by-step explanation:

    If we use the Pythagorean theorem, we can find if it is a right triangle. To do that, set up an equation.

    6^{2}+8^{2}=c^2

    If the triangle is a right triangle, c would equal 11

    Solve.

    36+64=100

    Then find the square root of 100.

    The square root of 100 is 10, not 11.

    So this is not a right triangle.

    I hope this helps!
