I've tried it an it just doesn't make sense to me. 
If someone could just explain it to me. I don't want you to give me to answer.

What part doesn't make sense? Like, does it not make sense what they're doing, or just thinking of the name of the property?

anonymous · Answer

I just started in Geometry and nothing makes sense. I can't think of the properties.

This is one of the ugliest web pages I have ever seen. However, it does have a nice list of properties. http://www.coolmath.com/prealgebra/06-properties/index.html

Thank you so much! I really appreciate it. I sucked at properties in Algebra1, but this should help a lot. :) Thanks again.
