Parallel and Perpendicular Lines

Curated and Reviewed by Lesson Planet

Enhance your class's understanding of linear equations by extending their study to parallel and perpendicular lines. Young mathematicians learn the relationship between the slopes of parallel and perpendicular lines. They then use that relationship by writing equations for parallel and perpendicular lines that pass through a given point.

Instructional Ideas

  • Post the lesson as a resource for absent students or those who need further explanation
  • Begin with an opener that allows pupils to discover the relationship between the slopes of parallel and perpendicular lines; provide them with several examples and ask them to determine the relationship

Classroom Considerations

  • Expects that the class is comfortable with writing linear equations with a given slope and y-intercept
  • Builds on the two previous lessons in a 20-part series

Pros

  • Provides practice with writing equations of parallel and perpendicular lines, including those that are horizontal and vertical

Cons

  • Does not provide an answer key for the practice problems
