Lines are everywhere around us in our daily life and they are part of our life. This blog helps kids to learn the different types of lines in our life and how and where they are used. Go ahead to explore. 

What is a Line?     

A line has length but no width. A line is a type of geometric figure that can move in both directions. A line is made up of an endless number of points.


Types of Lines

There are different types of lines used in Geometry. Lines are the foundation of the Geometry. Basically, there are two types of lines: Straight lines and Curved lines. 

Straight lines are further classified into Horizontal lines (Sleeping lines), Vertical lines (Sleeping lines) and Oblique lines (Slanting lines)

 

1. Horizontal line     

Horizontal line

Definition: A line that is parallel to x-axis is called as horizontal line.


Examples of horizontal lines

horizontal line example 

The red and white stripes in the flag are one of the examples for horizontal lines. Other popular examples include steps on the staircase, planks on the railway tracks.

     

2. Vertical line

vertical lines

Definition: A line that is parallel to y -axis is called as vertical line.

Examples of vertical lines

vertical line example 

The steel rails in a fence are an example of vertical lines. Even, a row of tall trees on a highway, Electric poles placed on the roads are examples of vertical lines. 


Other Types of Lines

When two or more lines are used together, they form different types of lines like parallel lines, perpendicular lines, and transversal lines as shown below. 

3. Parallel lines

When two lines that run together separated by the same distance and do not meet are known as parallel lines, irrespective of the length of the lines.

The symbol || is used to represent parallel lines. 

Real-Life Examples of Parallel Lines

Railway tracks are the best example to show the parallel lines. 

Walls of buildings, Stack of identical notebooks, collection of same-sized papers are all parallel to each item in the collection when arranged uniformly. 

 

4. Intersecting lines

Two non-parallel lines may meet at a point and those lines are called intersecting lines.

Real-Life Examples of Intersecting Lines

Examples of Intersecting Lines 

Scissors, the two blades of the scissors intersect at each other to make it work effectively.

Examples of Intersecting Lines

These signboards on the roads are one of the best examples to show the intersection of lines. 

 

5. Perpendicular lines

Perpendicular Lines

A line is said to be perpendicular to another line if the two lines intersect at a right angle. Perpendicular lines are denoted by the symbol of (⊥).

Real-Life Examples of Perpendicular Lines

 Examples of Perpendicular Lines 

Clocks are the best examples to show perpendicular lines at 3 O clock and 9 O clock. 

 Examples of Perpendicular Lines  Examples of Perpendicular Lines

The alphabets L and T are also one of the real-life examples of perpendicular lines. Television sets, bookshelves, and on the globe, where lines of latitude and longitude intersect are all examples of perpendicular lines. 

 

6. Transversal line      

Transversal line

The Transversal line is a straight line that cuts two or more lines which may or may not be parallel.      

Real-Life Examples of Transversal Line

Transversal line  Transversal line 

These are some of the examples of the transversal lines in our daily life, the antenna, stair railings. 

Apart from these, there are few more types of lines, about which the kids can explore such as skew lines, coplanar lines, concurrent lines, etc.


Conclusion

Lines are one of the important aspects and introduction to Geometry. With the types of lines introduced in this blog, kids will be able to apply their ideas to real life and explore their thoughts.
