Symmetry All Around uS

We know that a figure or a shape is said to be symmetrical, if it can be divided into two
identical parts by an imaginary line. This phenomenon is called symmetry.

The imaginary line is known as the line of symmetry.

We can see many symmetrical objects in our daily-life. Observe the following.

In the given figures, a line is dividing the figures into two equal halves. This line is called

line of symmetry.

line of Symmetry

An imaginary line which divides an object or a figure into two identical halves is called a
line of symmetry.
