Obtuse angle
Measures more than 90 degrees and less than 180 degrees
An obtuse angle is an angle that measures greater than 90 degrees but less than 180 degrees. It is formed when two lines or rays intersect and one angle between them is greater than 90 degrees. In other words, if one angle of a triangle is greater than 90 degrees, then the triangle is an obtuse triangle.
To visualize an obtuse angle, think of a clock face. If the minute hand is pointing to a number between 9 and 12, and the hour hand is pointing to a number between 1 and 6, then the angle between the hands is an obtuse angle.
Some real-world examples of obtuse angles include the angle between two walls in the corner of a room, the angle between the ground and a ramp leading up to a building, or the angle between the blade and the handle of a hoe.
It is important to note that an obtuse angle is not the same as a reflex angle, which measures greater than 180 degrees.
