Horizontal and Vertical Symmetry
Date: 10/27/2001 at 15:44:29 From: Lizzy 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?

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: ICEBOX, DECIDED, EXCEEDED, CHECKBOOK, OKEECHOBEE, HIDE, CHOICE Figure 2 on this Web page (Symmetry about the x-axis) shows horizontal symmetry: http://www.minerals.net/glossary/terms/s/symmetry.htm Some flags have horizontal symmetry; here are a few of them: Austria http://www.crwflags.com/fotw/flags/at.html Bahamas http://www.crwflags.com/fotw/flags/bs.html Bahrain http://www.crwflags.com/fotw/flags/bh.html Bangladesh http://www.crwflags.com/fotw/flags/bd.html Belgium http://www.crwflags.com/fotw/flags/be.html (You can find more from this page by clicking on the links under column A2): http://www.crwflags.com/fotw/flags/iso3166.html Does this help? - Doctor Sarah, The Math Forum http://mathforum.org/dr.math/
