Ch 17: Lines and Angles

About This Chapter

Review how to apply the Pythagorean Theorem and other principles of lines and angles to prepare for the SAT subject exam in mathematics. Video lessons and quizzes help you review plane Euclidean geometry in a simple and clear manner.

SAT Mathematics: Lines and Angles - Chapter Summary

Learn how to identify the various types of angles, tell whether two lines are perpendicular, and more using our online video lessons. Lessons in this chapter include:

  • Parallel, perpendicular and transverse Lines
  • Types of angles: vertical, corresponding, alternate interior and others
  • Angles and triangles: practice problems
  • The Pythagorean theorem: practice and application

Our online video instructors show you step-by-step how to apply your knowledge of lines, angles, and triangles to Euclidean geometry questions you find on the SAT mathematics exam. To help you prepare, video lessons include helpful features such as self-assessment quizzes and a written transcript.

SAT Mathematics Objectives

The SAT Mathematics Level 1 test is meant to be taken by students who've completed at least three years of college-prep mathematics, including two years of algebra and one of geometry. Students interested in pursuing STEM (science, technology, engineering, and mathematics), economics, and related degree programs in college might use the math exam to help their applications stand out.

You'll answer a total of 50 multiple-choice questions. Geometry and measurement account for 38%-42% of the exam, with plane Euclidean geometry accounting for 18%-22% of the total. The other geometry and measurement concepts you'll need to know for the test include coordinate geometry, 3-dimensional geometry, and trigonometry.
