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 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.
An angle whose measure is greater than 90° and less than 180° is called an obtuse angle. Learn more about obtuse angles, their properties, degrees, along with solved examples and practice questions.
Answer. Activity 3.1 Obtuse Angles. 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.
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.

An obtuse angle is an angle that measures greater than 90 degrees but less than 180 degrees. It is called “obtuse” because it is larger than a right angle (90 degrees) and does not form a straight line (180 degrees). To better understand this, let’s consider an example.
