This chapter discusses formula for calculating distance from a point to a line. It gives efficient formulae for the distance d1 between a point P and the line defined by points A and B, and the distance d2 between P and the line segment AB. An example of this application is an ...
(BTW - we don't really need to say 'perpendicular' because the distance from a point to a line always means the shortest distance.)This is a great problem because it uses all these things that we have learned so far:distance formula slope of parallel and perpendicular lines rectangular ...
