You should be able to:

1. Add to a 2-D figure so that it has reflection symmetry and draw in the line(s) of symmetry.
2. Add to a 2-D figure so that it has a rotational symmetry and show the center of rotation.
3. Describe all of the rotational and reflection symmetries of the 3-D object
4. Show how a 2-D object can tessellate the plane, using at least 10 copies, not all in a row.
5. Determine if a region will tessellate the plane and explain how you know this. Be very specific, using angles measures. Write in full, understandable sentences.
