The angle is less than 180 degrees, but more than 90 degrees.

Angles are usually measured in degrees and denoted by º (the degree symbol), which is a measure of circularity or rotation.

Answer: An obtuse angle is an angle whose measure is more than 90º and less than 180º

Let's see the classification of angles.

Explanation:

An obtuse angle is an angle whose measure is greater than 90º and less than 180º

Thus, the angle whose measure is less than 180 degrees, but more than 90 degrees is an obtuse angle.
