Lesson Plan: The Perpendicular Distance between Points and 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 calculate the perpendicular distance between a point and a straight line or between two parallel lines in space using a formula.
Objectives
Students will be able to
- calculate the perpendicular distance between a point and a straight line,
- calculate the perpendicular distance between two parallel lines.
Prerequisites
Students should already be familiar with
- calculating the dot and cross products of two 3D vectors,
- understanding and finding the equation of a straight line in space in different forms,
- understanding the relationship between straight lines in space (parallel or perpendicular).
