how do u do statements and reasons
Since this is not my area of expertise, I searched Google under the key words "geometry statements reasons" to get these possible sources:
http://en.wikibooks.org/wiki/Geometry/Chapter_2
http://mathforum.org/dr.math/faq/faq.proof.html
http://kitsilano.vsb.bc.ca/teachers/math/documents/Geometry%20notes.pdf
http://www.dummies.com/how-to/content/mastering-the-formal-geometry-proof.html
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
