Tell whether the triangle with the given side lengths is a right triangle. Justify your answer.
81 m, 91 m, 98 m

  1. Answer:
    The triangle specified is not a right triangle.
    Step-by-step explanation:
    The angles of a right triangle will always add up to 180 degrees. The angles specified add up to 270 degrees.
    There will also always be a 90 degree angle which makes up the right angle.
    Since there will always be a 90 degree angle, the other angles will have to add up to 90.
