Lizzie - Tessellation

This is a picture of pavement and its unique pattern keeps repeating itself. It doesn't overlap and it doesn't have gaps.

Brittany - Tessellations


A honeycomb is a mass of hexagonal wax cells. It is the same pattern over and over again. Therefore making it a tessellation.

TESSELLATIONS

BRITTANY:
A tessellation is a collection of plane figures that fills the plane with no overlaps or gaps.
Tessellations are seen throughout art history, from anciet architecture to modern art.

LIZZIE:
A tessellation is a repeating picture but turned differnt directions to fit together.
The word "tessella" means "small square."

ZAC:
Only 3 regualar tessellations exist: those made up of equilateral triangles, squares, or hexagons.
A semiregualar tessellation is made up of a variety of regualar polygons.

Zac - Symmetry

This is a great example of symmetry. You can fold the picture in half vertically and it will the same on both sides. This picture only has one line of symmetry.

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.
