18.4 Symmetry

We will discuss two kinds of symmetry:
1. line symmetry: reflection across a line of symmetry
- the image below has line symmetry, this is shown with the dotted lines

2. rotational symmetry: turning around a center point (point of rotation) and lining up again
-the flowers above also have rotational symmetry because you could turn them and have them line up again.

Check out these links from mathisfun.com for line symmetry and rotational symmetry
