Will Medal! Suppose a triangle has sides a, b, and c, and the angle opposite of the side of length a is obtuse. What must be true? A. b^2 + c^2 < a^2 B. a^2 + b^2 < c^2 C. b^2 + c^2 > a^2 D. a^2 + c^2 < b^2 ***My Answer: A*** Please Help!

    I am doubting myself... but I think I will go with A unless someone says otherwise. Help would be much appreciated!

    Well, it depends if you are looking at angles or side lengths

    I think that because we know that the angel is obtuse, we are looking at the side lengths?

    If you are talking about side lengths, then you should know that the sum of the legs of a triangle are always greater than the hypotenuse

    If I remember my geometry correctly, two legs are greater than the hypotenuse. However, I can't remember if that concept applies to all the lengths. So, with the little knowledge I gave you, if it even helped, I wish you luck :)
