Abstract
In the first drawings of a child, we often see flowers, butterflies,
leaves and so on. Have you noticed that they have intuitively
replicated the symmetry distributed everywhere in nature?
Let us understand the basics of symmetry first. What is
symmetry? How does a young child perceive it? Here is
a definition of symmetry from the Merriam Webster’s
dictionary – Symmetry is the property of correspondence in
size, shape and relative position of parts on opposite side of a
dividing line or median plane or about a center or axis.
Mathematically speaking we say an object is symmetric if it is
invariant with respect to a transformation. More specifically,
it means that after you transform the object it looks exactly
the same as its original version.
