Beauty of Symmetry

Beauty is symmetry and exactness. Symmetry has been inherently attractive to the human eye. Moreover,in the human body, symmetry is probably a good indicator of general health and strength.

To gauge how beautiful and appealing a work of art is we can use two parameters - complexity and order (or symmetry). If something is complex, it will be more appealing if it is less symmetrical. Else, if something is highly-symmetrical, it is better if it is less complex.

Symmetry has several variants, but the basic symmetrical operations are Translation, Rotation, and Reflection.

However, I think beauty is highly subjective. Whatever triggers your aesthetic sense should be defined as beauty.
