Question

Suppose a triangle has sides a, b, and c, and the angle opposite the side of length b is obtuse. What must be true?

Answer 1

what do you think?
if the angle opposite b was a right angle then b^2 = a^2 + c^2 (the pythagoras theorem)

Answer 2

as the angle opposite b is obtuse then would b be greater or smaller ?

Answer 3
