Tessellation- An arrangement of shapes closely fitted together, especially of polygons in a repeated pattern without gaps or over lapping.

~Here are some examples.

~Getting started~

~First we will open your GeoGebra app

~Then we make it a blank page by choosing blank page then getting rid of the grid by tapping the grid choice.

~Next we will create a rectangle. By first laying down a line. Then making another line parallel to your first line.

~Then we need to at points A and B make a perpendicular line.

~Now we are going to find the midpoint of all our lines and put a line through them.

~Next up we will get out our pen and draw our first line.
