obtuse angle
An angle between 90 and 180 degrees
An obtuse angle is an angle that measures greater than 90 degrees but less than 180 degrees. To put it simply, an obtuse angle is a wider angle than a right angle, which measures exactly 90 degrees.
One way to identify an obtuse angle is to look for an angle that is open or spreads out more than a right angle. For example, if an angle measures 120 degrees, it would be considered an obtuse angle because it opens up beyond the 90-degree mark.
It’s also important to note that an obtuse angle is different from an acute angle (which measures less than 90 degrees) and a straight angle (which measures exactly 180 degrees). Identifying and understanding different types of angles is an important concept in geometry and other areas of mathematics.
