### SYMMETRY

Reflectional Symmetry

Rotational Symmetry

Questions `

1) Identify all US states that have reflectional or rotational symmetry or both in their respective names

2) Identify symmetries for each letter in the alphabet.

3) Find a name in this class that has either reflectional or rotational symmetry.

4) Create 5 words that have rotational symmetry.

5) Create 5 words that have reflectional symmetry.

6) Create 5 words that have both symmetries.

**Consider capital letters when writing word formations.**

Project

1) Using the classical tools of geometry (compass and straightedge), construct a two-dimensional image for each type of rotational symmetry (orders 2 thru 8). You will need a protractor.

2) Find a real-world example for each type of rotational symmetry (orders 2 thru 8). (If using the Internet, list the URL address)

3) CHALLENGE: Using construction tools, produce at least 5 different three-dimensional images exhibiting rotational symmetry or reflectional symmetry or both. Images must be original!!!
