    Obtuse means larger than 90 degrees, so 123 degrees is obtuse

    Have you answered it as obtuse in your test ?

    Converse or inverse of a statement need not be true... what exactly is the complete problem ?

    the converse of the statement is true but the statement itself is false

    But I need to prove that it's not true.. Making if false is what I'm suppose to be doing and this is not a test I need help with homework this is homework

    Is the question: "Prove 123 deg angle is obtuse"?

    More than 90 degrees = Obtuse angle 90 degrees = Right angle Less then 90 degrees = acute angle 180 degrees = straight angle There is no way to prove that a 123 degree angle is not an obtuse, because it is and always will be an obtuse angle.
