In mathematics, “obtuse” is a term used to describe a particular type of angle
In mathematics, “obtuse” is a term used to describe a particular type of angle. An angle measures the amount of rotation between two intersecting lines or line segments.
An obtuse angle is an angle that measures greater than 90 degrees but less than 180 degrees. In other words, it is an angle that is wider than a right angle (which measures exactly 90 degrees), but not as wide as a straight angle (which measures exactly 180 degrees).
To identify an obtuse angle, you can visually examine the angle or use a protractor to measure its degree. If you have a triangle, for example, and one of the angles measures greater than 90 degrees, it is an obtuse angle.
It’s important to note that the sum of all angles in a triangle is always 180 degrees. Therefore, if one angle in a triangle is obtuse, the other two angles combined must be acute (measuring less than 90 degrees).
Understanding and identifying different types of angles, including obtuse angles, is fundamental in geometry and in various applications within mathematics and other fields of study.
