Lesson: The Perpendicular Distance between Points and Straight Lines in Space Mathematics
In this lesson, we will learn how to calculate the perpendicular distance between a point and a straight line or between two parallel lines in space using a formula.
Find, to one decimal place, the perpendicular distance from point to the line on points and .
Let be the line through point in the direction of vector . Find the distance between and the point , to the nearest hundredth.
Let be the line through the point that makes equal angles with the three coordinate axes. What is the distance between the point and , to the nearest hundredth.
