In short, we can make a tiny dot on a file by making use of a spicy pencilor a pointer of the needle. That is called a point. It to represent a position and ismarked by a capital letter A, B, C etc. A point has no size or shape. So, ~ above aline one infinite number of points exist.
Line: If two pointsare made at a street on a surface and also are joined by a pencil climate a part of aline is formed. The part of the line will be right if the surface is planeand curved if the surface is curved.
Thus, if we join any kind of two points with a ruler and extend iton both sides, a line is formed.
