The definition of an obtuse angle in geometry states that an angle larger than 90° but less than 180° is called an obtuse angle. We can use a protractor and mark any angle between 90° and 180° to draw an obtuse angle.

An obtuse angle is an angle with angle measure greater than 90° and less than 180°. In other words, it lies between 90° and 180°. So, what does an obtuse angle look like? How many degrees does an obtuse angle measure? Take a look at the given Obtuse Angle diagram to understand its range better.
Lines and angles. A line is an infinite number of points between two end points. Where two lines meet or cross, they form an angle. An angle is an amount of rotation. It is measured in degrees. Types of angles. Name of angle. Example.
An obtuse angle is the opposite of an acute angle. It is the angle which lies between 90 degrees and 180 degrees or in other words; an obtuse angle is greater than 90 degrees and less than 180 degrees.
The Obtuse Triangle has an obtuse angle (an obtuse angle has more than 90°). In the picture on the left, the shaded angle is the obtuse angle that distinguishes this triangle. Since the total degrees in any triangle is 180°, an obtuse triangle can only have one angle that measures more than 90°.
An obtuse angle has measure between \(90^{\circ}\) and \(180^{\circ}\). In this section we will define the trigonometric ratios of an obtuse angle as follows. Place the angle \(\theta\) in standard position and choose a point \(P\) with coordinates \((x, y)\) on the terminal side.
Obtuse triangle: a triangle with one obtuse angle. Right triangle: a triangle with one right angle. Exercises. True or False: Give a reason or counterexample to justify your response. An equilateral triangle is always acute. An obtuse triangle can also be isosceles.
