Transformations and SymmetryIntroduction

Many geometric concepts, like lines and points, were “invented” by mathematicians. Symmetry, on the other hand, is everywhere around us. Almost all plants, animals, and even we humans are symmetric.

Over time, we’ve imitated nature’s symmetry in art, architecture, technology and design. Symmetric shapes and patterns just seems to look more beautiful than non-symmetric ones.

But symmetry is much more important that simply looking beautiful. It lies at the very foundations of our universe, and can even explain the most fundamental laws of physics.

While symmetry is a very intuitive concept, describing it mathematically is more difficult than you might think. To start with, we have to learn about transformations.
