    If a triangle is made up of side lengths a, b and c

    Given that c is the longest side length of the triangle,

    The Pythagorean theorem can be used to tell if the triangle is obtuse, acute or right

    In an obtuse triangle,

    a^2 + b^2 < c^2

    In an acute triangle,

    a^2 + b^2 > c^2

    In a right angled triangle,

    a^2 + b^2 = c^2
