A triangle has side lengths of 18 cm, 80 cm, and 81 cm. Classify it as acute, obtuse, or right.

  • Geometry -

    for right-angled, is 81^2 = 80^2 + 18^2 ??

    for obtuse angle, 81^2 > 80^2 + 18^2

    notice two sides are almost equal, so it will look like an isosceles triangle

  • Geometry -

    the answer to this queston is acute! :)
