### What is Meant by Obtuse Angle?

In geometry, angle is the amount of rotation about the point of intersection of two lines (or planes) which is required to bring one in correspondence with the other. Based the measure (amount of rotation), different types of angles can be defined such as acute angle, right angle, obtuse angle and so on. If the measure of angle is greater than 90 degrees, then it is called an obtuse angle. If the angle value is less than right angle, i.e. 90 degrees, then it is an acute angle.
