Lizzie - Symmetry

The petals on the flower are symmetrical because they are the same no matter which way you divide them. Symmetry makes the flower look beautiful and we like beautiful flowers.

Brittany - Symmetry

This star has five lines of symmetry. You can cut it several differen ways and it will be the same. I like stars, especially purple ones as shown.

Symmetry

BRITTANY:
It's a thing of proportionality and balance.
It reflects beauty and perfection.

LIZZIE:
It's a pattern of self-similarity.
It can be proved by geometry and physics.

ZAC:
There are several kinds of symmetry, such as: reflection, rotational, and translational.
The most familiar type is geometrical symmetry.

Zac-Fractal

ZAC!!!!!

Koch Star: It is one of the earliest fractal curves that has been described. It has an infinite length because it goes on forever. It is based on the Koch curve.

Liz-Fractal

LIZZIE!!!!!

Menger Sponge: This is a fractal curve. It was first described by Karl Menger. It is a closed set.

Brit-Fractal

BRITTANY!!!!!

Sierpinski triangle: It was orginally constructed as a curve. It's one of the basic examples of a fractal. It was named after Polish mathematician Waclaw Sierpinski.

FRACTALS

BRITTANY:

It was coined by Benoit Mandelbrot in 1975.

Comes from the meaning "broken" or "fractured."

LIZZIE:

They are often considered infinitely complex.

Fractals came about in the 17th century by a man who mistakenly came up with it.

ZAC:

We use fractals for t-shirt and fashion and also for generations of new music and various art forms.

Fractals are easily found in nature, such as clouds.
