An obtuse angle is an angle with angle measure greater than 90° and less than 180°. In other words, it lies between 90° and 180°. So, what does an obtuse angle look like? How many degrees does an obtuse angle measure? Take a look at the given Obtuse Angle diagram to understand its range better.
The definition of an obtuse angle in geometry states that an angle larger than 90° but less than 180° is called an obtuse angle. We can use a protractor and mark any angle between 90° and 180° to draw an obtuse angle.
Obtuse Angle Definition. In Mathematics, “ an obtuse angle is an angle which is greater than 90 ° and less than 180 °”. In other words, an obtuse angle is between a right angle and a straight angle. Let us consider the below example,
An obtuse angle is more than 90° but less than 180° In other words, it is between a right angle and a straight angle.
An obtuse angle is also defined as an angle that is formed when a ray rotates between 90º and 180º around a point. This obtuse angle measures 130º. If you want to refresh your memory about how to measure an angle with a protractor, take a look at this video tutorial about measuring angles: Properties of an Obtuse Angle.
An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. This type of angle plays a key role in understanding various properties and relationships within geometric figures, particularly triangles, where the presence of an obtuse angle affects the classification and measurement of the triangle's angles.
An obtuse angle is an angle larger than a ninety degree angle and less than a straight line. Using degrees, an obtuse angle is greater than $90$ degrees and less than $180$ degrees. In radians, an obtuse angle measures more than $\frac {\pi} {2}$ radians and less than $\pi$ radians.
