Lesson Plan: Equations of Parallel and Perpendicular Lines Mathematics • Third Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to write the equation of a line parallel or perpendicular to another line.
Objectives
Students will be able to
- identify whether two given lines are parallel, perpendicular, or neither,
- find the equation of a line that is parallel to a given line,
- find the values of the unknown coefficients in the equations of two parallel straight lines,
- use the relationship between the gradient of perpendicular lines in order to find the slope of a line given a line perpendicular to it,
- find the equation of a line that is perpendicular to a given line,
- find the values of the unknown coefficients in the equations of two perpendicular straight lines.
Prerequisites
Students should already be familiar with
- the definitions of the terms parallel and perpendicular,
- the slopes of parallel and perpendicular lines,
- writing the equation of a line given the slope and the -intercept,
- writing the equation of a line given the slope and a point on the line,
- writing the equation of a line given two points on the line.
Exclusions
Students will not cover
- vector equations of straight lines,
- parametric equations of straight lines.
