The Aims of the project

Learn what the symmetry is.
What are the types of symmetry.
What does the kind and class of symmetry mean.
View the examples of products with different kinds of symmetry.

We tried to find out what is the symmetry, its kinds and to find the products that have symmetry.

The type of symmetry or class of symmetry is a group of the elements which are completely describing symmetry of this or that polyhedron. Let's consider some types of symmetry. For this purpose we can use the products from beads.

The butterfly represents an example of mirror symmetry.
The simplest type of symmetry. If the object or a figure can be divided by the plane into two halves so that these halves become equal it is a mirror symmetry. The example of such a symmetry is a human body, bodies of animals and many others.
Mirror symmetry helps to create the impression of steadiness and rest as it makes both halves of the image equivalent for our eyes.

A handful of grapes have different kinds of symmetry.

Rectangle and rhombus are non squares, which have two axis of symmetry, and the square - four axes of symmetry

There are figures, which do not have any axis of symmetry. These figures include a parallelogram.

Let's look at our handmade products from beads ...
