About This Chapter

The Parallel Lines and Polygons chapter of this High School Geometry Tutoring Solution is a flexible and affordable path to learning about polygons and parallel lines. These simple and fun video lessons are each about five minutes long and they teach all of the operations involving parallel lines and polygons required in a typical high school geometry course.

How it works:

  • Begin your assignment or other high school geometry work.
  • Identify the parallel lines and polygons concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our high school geometry tutoring solution will benefit any student who is trying to learn about parallel lines and polygons and earn better grades. This resource can help students including those who:

  • Struggle with understanding how to proves lines are parallel, methods for measuring polygons, identification of regular polygons and their parts, or any other parallel lines and polygons topic
  • Have limited time for studying
  • Want a cost effective way to supplement their math learning
  • Prefer learning math visually
  • Find themselves failing or close to failing their parallel lines and polygons unit
  • Cope with ADD or ADHD
  • Want to get ahead in high school geometry
  • Don't have access to their math teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about parallel lines and polygons simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live algebra tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about parallel lines and polygons on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning objectives

  • Study angles that are formed by parallel lines.

Angles Formed by a Transversal

1. Angles Formed by a Transversal

When you have a pair of parallel lines and a transversal, something very interesting happens to the angles that are formed. You can see this happen in real life at street intersections and such. Watch this video lesson to learn about all of this.

Parallel Lines: How to Prove Lines Are Parallel

2. Parallel Lines: How to Prove Lines Are Parallel

Watch this video lesson to learn how you can prove that two lines are parallel just by matching up pairs of angles. Learn which angles to pair up and what to look for.

Using Converse Statements to Prove Lines Are Parallel

3. Using Converse Statements to Prove Lines Are Parallel

Because a pair of parallel lines produces unique angle characteristics, we can use this information to our advantage. Watch this video lesson to see how we turn this advantage into converse statements to help us prove parallel lines.

Constructing a Parallel Line Using a Point Not on the Given Line

4. Constructing a Parallel Line Using a Point Not on the Given Line
