No, an obtuse angle is between 90-180 degrees if it is 180 degrees it is an straight angle, while if it is 90 degrees it is a right angle

They are both angles.....acute is smaller than ninety degrees and obtuse is larger/wider. They aren't alike in a lot of ways though.
If you mean how many degrees usually goes into an obtuse angle, most angles above ninety (90) degrees is and not equal to one hundred eighty (180) degrees is considered obtuse.
obtuse angles are larger than 180 degrees. acute are smaller than 180. for example ina trangle, the exterior angles are obtuse and the inner angles are acute.
Acute angles are angles less than 90 degrees an obtuse angles are greater than 90 degrees
There are two types of angles that are smaller than 180 degrees: acute and obtuse. Acute angles are those that are smaller than a right angle (90 degrees) and obtuse angles are those that are larger than a right angle but smaller than 180(ex: 100 degrees, 91 degrees, etc.) Obtuse and acute angles are easy to identify without actually using a protractor; they are usually exaggerated on tests and assignments. On top of that 180 degree angles are called straight.
