Objective: We are belongings with three dimensional object. Those objects have their shape and size. Their shape is framed by the rule of a function of three variables. So to understand our surroundings, we must go through the three dimensional geometry and concept behind it. In this scope our aim to study the three dimensional system, plane and and straight line. We have discussed elaborately about the concept of direction cosines and direction ratios of a straight line and use of it. The behaviour of a straight is totally depends on the direction. Also one can observe that different surface can be generated by the straight line which will provide how three dimensional shape is generating.
