Which type of angle measures more than 90 degrees but less than 180 degrees?

An angle that measures more than 90 degrees but less than 180 degrees is classified as an obtuse angle. This range defines obtuse angles, distinguishing them from acute angles, which measure less than 90 degrees, and right angles, which measure exactly 90 degrees. A straight angle, on the other hand, measures exactly 180 degrees. Understanding these definitions helps clarify why obtuse is the appropriate term for angles within this specific measurement range. This knowledge is fundamental in geometry, as it allows for better identification and categorization of angles based on their measures.
