Symmetry: A figure is said to be symmetrical if one half of the figure is a mirror image of the other.

Depending on the lines of symmetry, symmetrical figures can be classified into:

No Line of Symmetry (for the asymmetrical figure)
One Line of Symmetry
Two Line of Symmetry
Multiple (more than 2) Line of Symmetry
Infinite Line of Symmetry
