# Mathematics in Everyday Life

It is sometimes difficult for students to appreciate the importance of Mathematics. They often find the subject boring and hard to understand. With this project we will hopefully help our students realise that Mathematics is not just a subject on their time-table but a tool they use in their everyday life!

### Symmetrical Objects

*Pottery*The ancient Chinese used symmetrical patterns in their bronze castings since the 17th century B.C. Bronze vessels exhibited both a bilateral main motif and a repetitive translated border design. Persian pottery dating from 6000 B.C. used symmetric zigzags, squares, and cross-hatchings.

A long tradition of the use of symmetry in rug patterns spans a variety of cultures. American Navajo Indians used bold diagonals and rectangular motifs. Many Oriental rugs have intricate reflected centers and borders that translate a pattern. Not surprisingly most rugs use quadrilateral symmetry -- a motif reflected across both the horizontal and vertical axes.

### Symmetrical Nature !

The Word Symmetry is often used in everyday language, and usually by people of all ages can recognise symmetry when they see it.

Symmetry in nature is most often Bilateral symmetry. This means that the two halves of an object are exact mirror images of each other.

*Symmetry In the Animal Kingdom…*

… in humans- the human face also has a line of symmetry in some places, but some faces are more symmetrical than others. There are also other examples of symmetry in the human body like the kidneys, lungs and the brain. This applies to most animals in the animal kingdom.

*Symmetry In Plants...*

… in flowers there are roughly identical petals, sepals, stamens and leaves.

*Symmetry at the Beach…*

… at the beach there are a variety of shells and underwater life with a line of symmetry, an example of which is a crab or a starfish.

### Symmetry Around US

*in Nature

*in Clothing

*in Architecture

*in Art

Symmetry is a type of visual balance where the overall composition is arranged to look like it is the same on both sides of the center of the design.

*If you folded this snowflake in half, both sides would match up perfectly*.

In other words, symmetry is a design which could be folded in half, and as the design folds, each part of the design would match up with the half on the opposite side of the center.
