Solution
We have to arrange the given shapes according to the number of lines of symmetry they have.
Let's take parallelogram first.
As we can see, the halves in parallelogram are not mirror halves and they can’t exactly overlap each other.
Hence, parallelogram has zero line of symmetry.
So it will come first.
Let's take kite now.
A kite has only one line of symmetry as shown above.
So it will come at second place.
Let's take rhombus now.
A rhombus has two lines of symmetry along the diagonals.
Hence, it will come at third place.
At last, we will take a circle.
In a circle, each diameter is considered as a line of symmetry. Since an infinite numbers of a diameters can be drawn in a circle, we can say that a circle has infinite lines of symmetry.
Hence, it will be at last in the order.
So,the arrangement will look like:
Parallelogram
Kite
Rhombus
