# Ch 10: Honors Geometry: Parallel Line Proofs

Explore the information in this chapter as you learn about how to determine if two lines are parallel. Analyze the transcripts to review key definitions for related terms, then test your knowledge by taking the chapter exam.

## Honors Geometry: Parallel Line Proofs - Chapter Summary and Learning Objectives

Parallel lines can be seen everywhere around us, from the lines marking traffic to artistic patterns, but what proof is there that these lines are truly parallel? In this chapter you will discover the proofs used to establish whether two lines are mathematically parallel to one another. Video lessons within the chapter allow you to see parallel line proofs in action. The quizzes available at the end of each lesson can help you gauge whether you have understood the materials. Topics covered in this chapter include:

• The angles of parallel lines
• The characteristics of parallel lines
• Proofs and indirect proofs
• The Parallel Postulate
• Transverse, perpendicular, and parallel lines

Video Objective
