There was school the nextday as usual but the good thing was you had an art class. You were all sad after your Math class as none of you really understood solid shapes. The teacher realized that something's bothering you all and found out the reason. He thought he would explain you the same with drawing.
He took a chalk and started to draw a shape. Before that he asked a question, "To draw something I put the chalk on the board making a point. The point has ____ dimension”.
0
When he puts the chalk on the board it becomes a point and can be extended from that point. Point has no dimension i.e., 0 dimension.
