Let us now discuss some basic concepts of Symmetry.

### Symmetry in Mathematics

In Mathematics, one shape is exactly similar to the other shape when it is either flipped, moved, or rotated. For example, when you are being asked to cut out a heart drawn on a piece of paper, don’t you just wrap the paper, draw one half of the heart at the fold, and cut it to find that the other half of the heart that matches exactly the first half of the heart. The two identical parts of this heart-shaped paper cut-out is an example of symmetry. The definition of symmetry states that “symmetry is a mirror image”. If the image looks exactly the same when it is turned or flipped, then it is known as symmetry.

### Line of Symmetry

The imaginary line or axis along which you wrap a figure to get the symmetrical halves is known as the line of symmetry. The line of symmetry is also termed as the axis of symmetry. The line of symmetry is also termed a mirror line because it has two reflections of a shape meeting at it. Hence, the line of symmetry is a type of mirror. Line of symmetry divides an object into two halves. There can be either one or more than one line of symmetry. Practically, a shape may have:

No line of symmetry.

An infinite line of symmetry.

One line of symmetry.

Two lines of symmetry.

Multiple (or more than two) lines of symmetry.

### Constructing Lines of Symmetry

A line of symmetry divides the object into two halves. An object can have one or more than one line of symmetry,

Look at the square below. How many lines of symmetry can you see?

We can see 4 lines of symmetry in the square.

Look at the rectangle below. Does the rectangle have the same number of lines of symmetry as square? Remember, the line of symmetry divides a figure into two halves so that each piece looks exactly the same. You can see that a rectangle has fewer lines of symmetry. Can you think of a direction in which the line of symmetry cannot proceed further?

A rectangle cannot have a diagonal line of symmetry like a square because the sides of the rectangle are not of equal length. If the rectangle is folded diagonally so that vertex A meets vertex D, the sides would not match. You can try this with a piece of paper.
