# Types of Lines

What are the different types of lines?

All plane shapes are made up of straight or curved lines or combination of both.

There are two different kinds of lines.

1. Straight line:

Straight lines are shown below. 2. Curved line:

Curved lines are shown below. 1. Straight Lines:

Observe the edge of this page. Place a ruler along its edge. All its edges are straight line. Straight lines may be drawn in different directions and are given three names. There are three different types of straight lines:

(i) Horizontal lines: The lines drawn horizontally are called horizontal lines. (ii) Vertical lines: The lines drawn vertically are called vertical lines. (iii) Oblique or slanting lines: The lines drawn in a slanting position are called oblique or slanting lines. The explanations on different types of lines will help the kids to understand the difference between the straight lines and the curved lines and how the lines are drawn in different directions in geometry.

2. Curved Lines:

It is an object similar to line but not straight.

Let us understand the lines with an activity.

Andrew wanted to understand the straight lines and curved lines. His teacher told him to write his name in capital letters and observe each letter carefully.

A          N         D         R         E         W

Andrew was happy that his name contains alphabets made up of different types of lines.

 Alphabets A, N, E and W are written with horizontal, vertical and slanting lines. Alphabets like D and R are written with curved lines.

Questions and Answers on Straight Lines and Curved Lines:

1. Observe the number train carefully. Cross the numbers which are made up of only straight lines, tick the numbers which are made up of only curved lines and circle the numbers which are made up of both straight and curved lines.

2. In the given picture color the horizontal lines blue, slant lines red, vertical lines orange and curved lines green. Also write the number of lines in the given space.
