An obtuse angle is any angle greater than 90 degrees and less than 180 degrees. Yes. An obtuse angle is geometrically greater that a right angle. Any number degree larger than â¦ 90 degrees is obtuse, as any number degree lesser than 90 degrees is acute.
Angles can be measured in degrees or radians. For the time being, we will strictly talk about angles in terms of their degree measure. The symbol for degrees is Â°. Angles can measure from 0Â° up to 360Â°. Angles with no measure are called zero angles, while angles of 360Â° are full rotations. For our study of geometry, we will primarily focus on three important classifications of angles: acute, obtuse, and right.
