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.
