Damn, why does everyone seem to think I am in high school cause I ask a math question? There must be many here who are proficient in geometry in their adult lives. Oh well, I am not. Didn't get it then, still don't get it now. I am 28 years old, and in a college level MAT 140 class. Don't worry, I will direct any further questons to a homework helpsite to avoid any further issues. But just so you know........there are people past 18 who are still in school, usually it is called college, and not everyone is great at every subject there is.

To those who have offered assistance, without assuming I am under 18--thank you very much, it is much clearer now, and I appreciate it very much, especially since some of the responses looked time consuming.
