A point according to Euclid has no part. A point in two dimensional coordinate plane in coordinate geometry is represented by $(x,y)$. The horizontal component is denoted by $x$ and the vertical component is $y$.
Line by definition is a infinite length single dimension geometrical object. It was first defined by Euclid in his book ELEMENTS as a straight line is of a breathless length where all its point are on itself.
In this lesson we shall look into find a formula to find the shortest distance between a point and a line.
