Ch 12: Lines and Angles in Geometry

About This Chapter

This chapter uses videos developed by our expert instructors to teach students about lines and angles in geometry. You can use the quizzes associated with each lesson to ascertain whether or not you understand the math concepts being presented.

Lines and Angles in Geometry - Chapter Summary and Learning Objectives

Parallel and perpendicular lines, as well as angles, all follow exact geometric principles. Our instructors provide video lessons that are around 5 minutes long to guide you through focused segments of geometric angle concepts to ensure you can make sense of lines and angles in geometry. We provide tools to enhance your user experience, such as video transcripts and the ability to ask the instructor a question. The lessons help you understand the following:

  • Parallel, perpendicular and transverse lines
  • Line segments and rays
  • Different types of angles

Video Objective
