Point

Point indicates the location on the plane. When we talk about a point on the plane, it can be indicated by a small decimal, which can not be further broken.  We us a point to locate the position on the plane, so we say that a point is used to mark the position which is marked with the respect to x and y axis. In case we have many collinear points on the plane, then we say that the line is formed by joining these points.

In order to find the location of a point on the plane, we will relate it with the coordinates of x axis and y- axis. Thus we say that  the coordinates of x , y axis of the point can be written which shows that the point exist at a particular place which has a particular location.  We always represent the point on the plane by the capital letters say Point A, B, C etc.

 If  we say that the point on the plane exist at the position ( 3 , 2), it simply means that the point  is at the distance of 2 units from the origin towards the x axis and it is at the distance of 3 units towards y axis. (know more about Point, here)

An interesting fact about the point is that  if a point is drawn on the plane then infinite number of lines can be drawn from that given point.  Also if we have two given points, then we can only draw one and only one line which can pass through the two given points. In case we have 3 points and one line is drawn passing through the tree given points, it simply indicates that the three lines are collinear, otherwise  3 line segments will be drawn passing through the given  lines and the closed figure so formed will be  called as a triangle.
