Mark two distinct points A and B on the plane of your note book. Can you draw a line passing through A and B? By experience we find that we can draw only one line through two distinct points A and B. Hence "Given any two distinct points in a plan..

A ray can be extended in one direction only. Its other end is a fixed point..

The position of the point P in a plane in the rectangular co-ordinate system is determined as follows: Draw PA and PB perpendicular to XX' and YY'. The segment OA = a measures the distance along the x-axis (the x-coordinate and the perpendicular distance AP = OB = b ( parallel to y - a..
