# Ch 3: Prentice Hall Geometry Chapter 3: Parallel and Perpendicular Lines

The Parallel and Perpendicular Lines chapter of this Prentice Hall Geometry Textbook companion course helps students learn essential geometry lessons of parallel and perpendicular lines. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the parallel and perpendicular lines textbook chapter.

## How it works:

• Identify the lessons in the Prentice Hall Geometry Parallel and Perpendicular Lines chapter with which you need help.
• Find the corresponding video lessons within this companion course chapter.
• Watch fun videos that cover the parallel and perpendicular lines topics you need to learn or review.
• Complete the quizzes to test your understanding.
• If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.
