Classnotes-
Today we discussed the relationships of the sides of special right triangles.
( 30-60-90 and 45-45-90 ) This material can be found in your textbook in Section 9-4
Pay special atention to the information in the green box on p. 551 as well as examples 1 - 3 in
that section. Homework included p. 554 ( # 9 - 20 ) . Also, students discussed doing the artwork
with their tessellations in Christmas theme in order to use them in the Christmas theme door
contest. That is optional. Students also worked on tesselations again today.

Tessellation- a collection of tiles that fill a plane with no gaps or overlaps. ( see pp. 452-453 in text )
A famous mathematician/ Artist that worked with tessellations was M.C. Escher. We viewed some of his work from the following sites and observed how some tiles were translated while others were reflected and rotated in the plane.

Today we created our own original shape ( tile) which we will use tomorrow to tessellate ( or tile ) a plane ( sheet of poster board) to create our own piece of artwork. This tessellation will be worth 50 test points. We used the directions from the following video and made sure to listen carefully to ensure our shape contained the properties which would allow it to tesselate. We watched the video all the way through first and then watched it a second time stopping it between each step to actually make the tile.

Bonus points will be given if you create your shape from a hexagon instead of a triangle ( using the same procedure)
.
