### INTRODUCTION

Poly Gon is having a math party. She is going to send out invitations to all her friends. She wants her invitations to be decorated with lots of shapes.

Your job is to design the invitation for Poly's party. The invitation can have lots of colours and use many different effects, but it must follow these rules:

•  Three shapes must be similar.

•  Two shapes must be trapezoids.

•  One shape must have 2 parallel sides.

•  Two shapes must be congruent.

•  One shape must have less than 4 sides.

•  One shape must have more than 4 sides.

Describe completely the different shapes you used in your design. To create your invitation, you will download a drawing program from the Internet.

### THE PROCESS

1. Go to Tux Paint. You will have to download this program from the Internet, using the following steps.

ii. Click on the web address under tuxpaint windows installer .

iii. On this screen you must select a mirror. You should pick the mirror that is at a location close to where you live. Which one do you think is the best choice? Check with your teacher before you click on one of the choices under the title download.

v. It will ask you if you should OPEN or SAVE the file to your computer. Check with your teacher, and then click on the correct one.
