Lesson Plan: Angle between Two Straight Lines in the Coordinate Plane Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the measure of an acute angle between two straight lines in the coordinate plane.

Objectives

Students will be able to

  • find the angle between two straight lines in the coordinate plane given their slopes, two pairs of points, or equations,
  • find the equation of a line given the equation of another line and the angle between them.

Prerequisites

Students should already be familiar with

  • finding the slope or direction vector of a line from its (Cartesian, vector, or parametric) equation.

Exclusions

Students will not cover

  • finding the angle between lines in space.
