An obtuse angle is defined as an angle that measures more than 90 degrees but less than 180 degrees. This type of angle is larger than a right angle, which measures exactly 90 degrees, and smaller than a straight angle, which measures exactly 180 degrees.

Understanding the classification of angles is essential in geometry. Acute angles, for instance, are those that measure less than 90 degrees, while straight angles represent a full straight line at 180 degrees. Recognizing how obtuse angles fit into the larger framework of angle properties allows for a clearer grasp of concepts related to shapes, triangles, and various geometric constructions.
