Horizontal and Vertical Symmetry

Subject: Symmetry

I have a project where I have to look for things outside that involve 
symmetry. One of the things I have to find is an example of 
horizontal symmetry, and I have no idea what that is. I tried to look 
it up in a dictionary but it just is not making any sense.

Can you please help me?

Hi Lizzy - thanks for writing to Dr. Math.

Let's take some simple examples:
VERTICAL SYMMETRY: if you draw a vertical line    |

down the middle of an object with vertical symmetry, the two sides 
will be mirror images of each other.

   Examples of capital letters that have vertical symmetry are:

      A H I M O T U V W X Y

HORIZONTAL SYMMETRY: if you draw a horizontal line  ______________

across the middle of an object with horizontal symmetry, the top will 
be a mirror image of the bottom.

   Examples of capital letters that have horizontal symmetry are:

      B C D E H I K O X

   Words with horizontal symmetry include:


Figure 2 on this Web page (Symmetry about the x-axis) shows horizontal 

Some flags have horizontal symmetry; here are a few of them:

Does this help?
