Symmetry and patterns

Symmetry

Have you looked carefully at some beautiful objects around you? The beauty of some objects is because of their symmetry.

In mathematics, in a particular pattern in which we can draw a central dividing line on a the shape or object, and it gives two exactly same sides is called Symmetry and the shape or object is called symmetrical.

Look into the picture below.

Boy

The body of the butterfly is made in such a way that it can be divided identically into two parts. The body of the butterfly is called symmetrical shape.

Boy

The blue dotted line divides the body of the butterfly into two identical parts. Blue line is called the line of symmetry.

Now, did you understand the definition of the symmetrical shape and line of symmetry?

Types of lines of symmetry

We have learned that the line of symmetry is the line that divides the object into two identical halves.

There are three types of lines of symmetry:

  • Horizontal line of symmetry
  • Vertical line of symmetry
  • Diagonal line of symmetry

Horizontal line of symmetry:Is the line that runs across the image.

Boy

Vertical line of symmetry:Is the line that runs down the image.

Boy

Diagonal line of symmetryIs the line that runs across the diagonal corners of the image.

Number of lines of symmetry

Some of the objects may have one, two, three, or multiple lines of symmetry.

Let us see the examples of some objects.

1. One line of symmetry

Boy

2. Two lines of symmetry

3. Three lines of symmetry

4. Four lines of symmetry

Boy

5. Five lines of symmetry

Boy

6. Six lines of symmetry

Boy

7. Seven lines of symmetry

Did you know?

Taj Mahal is a symmetrical monument. That property makes it beautiful.
