Mathematics Knowledge 
As an ASVAB tutor, I review various subtopics in Mathematics Knowledge.
One of those subtopics is angles and slope. Angles is a geometry question.
Yesterday I presented a Mathematics Knowledge question on angles. I remind my students about acute angles, right angles, and obtuse angles.
The question is about acute angles.
Which of the following is an acute angle?
- 45 degrees
- 90 degrees
- 135 degrees
- 180 degrees
Do you know the definition of an acute angle?
An acute angle is less than 90 degrees.
The correct answer is choice A. 45 degrees.
