What is the angle of 190 degrees?
This is a superior angle.
An obtuse angle is defined as an angle greater than 90 degrees and less than 180 degrees, and an angle greater than 180 degrees is not an obtuse angle.
Within the range of less than one fillet, those larger than one right angle are called "upper angle" and those smaller than one right angle are called "lower angle" (corresponding to the concept of upper arc and lower arc); Within the range less than right angle, those less than right angle are called acute angles, and those greater than right angle are called obtuse angles.
