Hello, I am a new member. I joined because I do not understand Geometry. My teacer is terrible, he doesent except questions, he just lectures us. As of right now I am passing but by the skin of me teeth. I am having a test on chapter 10 called Quadrilaterals. I really don't understand any of it because my teacer does a poor job getting his point across. What I really need help on is prooving quadrilaterals are parallelograms. I am lost when it comes to this. Here is a link to the chapter I am working on : http://www.herricks.org/files/11368/Chapter10.pdf
I need to understand things like on page 387
& how To find areas of a polygon, etc.
Please view the textbook so you know exactly what I'm dealing with.
i just can't seem to wrap my head around it.
My test is Tuesday, please help me !!
