Lines and point


In simple language, it can be said that a line is a long and thin mark. It can be seen easily as the length of a table, the length of pipes or trees, loose skipping ropes, etc.

G2_1_Lines and point_Lines

There are two types of lines that can be seen in our surroundings.

  • Straight Lines
  • Curved Lines

Straight Lines

A straight line is just a line with no curves. Fold a paper sheet in half. If we run a pencil along the fold from the top to the bottom, then we get a straight line.

G2_2_Lines and point_Straight line

A straight line can be drawn in three ways.

  • Horizontal lines (also called Sleeping lines)
  • Vertical lines (also called Standing lines)
  • Slant lines

Horizontal Lines or Sleeping Lines:

These lines can be seen from the edge of a diary, brick, eraser, etc.

Curved Lines

A line with the curve is called a curved line. These lines can be seen easily in ropes, skipping rope, rope bridges, arch of windows, etc.

G2_6_Lines and point_Curved lines


A point is a dot or a full stop. In real life, we can see that four leaves meet at one dot. This dot is said to be a point. A Point can be easily seen in road junctions also.
