Lines and point

Lines

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.

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.

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.

Vertical Lines or Standing Lines:

These lines can be formed from the edges of the stems of trees, wickets, buildings, etc.

Slant Lines:

These lines can be seen in the staircase, roof of huts, 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.

Point

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.
