all sides different lengths name the polygon8
Are you talking about an 8-sided figure?
Since this is not my area of expertise, I searched Google under the key words "polygon names" to get these possible sources:
http://en.wikipedia.org/wiki/Polygon
http://www.pubquizhelp.34sp.com/sci/polygon.html
http://mathforum.org/dr.math/faq/faq.polygon.names.html
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
