Which is an acute angle?

  1. 30 degrees
  2. 90 degrees
  3. 120 degrees
  4. 180 degrees

As an ASVAB tutor, I teach my students about angles to prepare them for the Mathematics Knowledge section of the ASVAB.  The topics of angles and slope is one of the 15 subtopics that I cover in my review of Mathematics Knowledge.  I have included a review of angles in my book, The ASVAB Tutor’s Mathematics Knowledge Study Guide.  It is important to know the different types of angles including acute, right, obtuse, complementary, supplementary, etc.

Do you know what an acute angle is?
