Basic Symmetry

Basic Symmetry

This has pictures in it to aid you in answering these questions (well actually the questions wouldn't make sense without them...), and none of them are difficult to understand (well they are just shapes). Have fun!

Look at these shapes. Decide which shape or shapes fit each description and type the letter or letters for your answer.

1. Three lines of symmetry
2. No reflection symmetry
3. Four lines of symmetry
4. Rotation symmetry of order three
5. Rotation symmetry of order two but no reflection symmetry
6. One line of symmetry
7. Rotation symmetry of order four but no reflection symmetry
8. No rotation symmetry
9. Rotation symmetry of order two
10. Rotation symmetry of order three but no reflection symmetry

Re: Basic Symmetry


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Basic Symmetry

Thats great. I really like the information shared for the symetry.
But symetry is required when you are working on the plane curves.
