why was symmetry made for ?......

There are various things around us which are symmetrical. Few symmetrical things around us are as follows:

leaves of trees or plants, model of a car, chocolate, CD etc.

In order to study the pattern in those particular things, symmetry is designed.

Symmetry is very useful in designing the models of different things such as cars, aero planes, tiles, buildings etc. It makes things look good and helps them to maintain the balance.

It is also used in architecture for construction of monuments and buildings as well as in studying advanced Science and Mathematics.
