Yesterday I presented a question on obtuse angles.
Which is an obtuse angle?
- 45 degrees
- 90 degrees
- 135 degrees
- 180 degrees
I cover the topic of angles and slope in my book entitled, The ASVAB Tutor’s Arithmetic Reasoning Study Guide. Obtuse angles are angles that are bigger than 90 degrees but less than 180 degrees. An angle less than 90 degrees is called an acute angle. A 90-degree angle is called a right angle. An angle that is 180 degrees is a straight line. Did you know what an obtuse angle is?
