Ch 19: ASVAB Math: Geometry

About This Chapter

Brush up on your knowledge of geometry to prepare for the ASVAB exam. Use our thorough video lessons to learn all you need to know about geometrical figures and how to determine their elements.

Geometry - Chapter Summary

Geometry can seem intimidating, especially since you're dealing with the properties of so many different shapes and figures. We'll make geometry feel easy as pie (or pi) by walking you through the elements of different geometrical figures and showing you how to use those elements to solve math problems. Prior to taking the ASVAB exam, explore the world of points, lines, angles, and two- and three-dimensional shapes until you achieve a greater understanding of basic geometry. These lessons cover:

  • Different types of angles
  • Perimeters and areas
  • Properties of different triangles
  • Similar triangles
  • The Pythagorean theorem
  • Surface-areas and volumes
  • Perpendicular and parallel lines
  • Pyramids, cones, spheres, rhombuses and cylinders

Our video lessons, developed by a team of awesome instructors, are a great way to learn everything you'll need to know before test day. Use our video transcripts to go over what you've learned and then check out the self-assessments to get a feel for the types of questions you may encounter on the ASVAB.

ASVAB Math Objectives

The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple-choice exam used to test aptitude in certain areas for applicants to the U.S. military. A paper-based Mathematics Knowledge subtest of the ASVAB is comprised of 25 questions, many of which will test your knowledge of geometry, that you will have 24 minutes to complete. There is also computerized version of the test. It has 16 questions that must be answered in 20 minutes. The questions in this subtest account for just over 11% of the exam. Objectives for this chapter include:

  • Defining different types of angles and lines
  • Identifying two-dimensional shapes and demonstrating how to calculate their perimeters and areas
  • Knowing how to use the Pythagorean theorem to work with triangles
  • Calculating the surface areas and volumes of different three-dimensional shapes

Getting a handle on geometry with our effortless video lessons will help you greatly in the math section of the ASVAB exam. By the time you're done with our study guide, you'll be ready to take on any geometry questions on the test.
