obtuse angle
a triangle with one angle that is > 90 degrees
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 but narrower than a straight angle.
The word obtuse in geometry is derived from the Latin word obtusus, which means blunt. Thus, an obtuse angle is commonly referred to as a blunt angle because of its width.
To identify an obtuse angle, you can use a protractor or any other geometrical tool that measures angles. If the angle measures between 90 and 180 degrees, it is an obtuse angle.
Some examples of obtuse angles include the angle formed between the hands of a clock at 4:10, the angle formed between two hands when clapping, and the angle formed between the floor and the ceiling in the corner of a room.
It is important to note that an obtuse angle is different from an acute angle, which measures less than 90 degrees, and a right angle, which measures exactly 90 degrees.
