Most dictionaries define acute angles and obtuse angles in terms of degrees. Restate these definitions in terms of radians

Acute and obtuse angles are simply below and greater than 90degrees, right? Acute angles mean <90degrees, obtuse means >90 degrees?

So, we basically want to change 90 degrees into radian form; them, we can say that less than that is acute and more than that is obtuse.

To convert degrees to radians, multiply the number of degrees by pi / 180degrees

90 degrees, then becomes (90)* [pi/(180)], or (1/2) pi.

So acute angles are less than 1/2 pi and obtuse angles are greater than 1/2 pi
