Lesson Plan: Angle between Two Straight Lines in Space Mathematics • Third Year of Secondary School
This lesson plan includes the objectives and prerequisites of the lesson teaching students how to find the angle between two straight lines in three dimensions using the formula.
Objectives
Students will be able to
- find the angle between two lines given their direction vectors, ratios, or cosines using the appropriate formula,
- find the angle between two lines given their Cartesian, parametric, or vector equations.
Prerequisites
Students should already be familiar with
- finding equations of straight lines in space,
- 3D vectors and operations on vectors,
- calculating the scalar product of two vectors.
