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.

• 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.
