geometry proofs
Okay everyone when it comes to math I am well not bright. So I need a lot of help. I am currently trying to graduate from High school. It is long over due. I need help with my math. I have alot of questions.

Here are a couple.

1.)Name the property of equality that justifies the statement:
If AB = CD and CD = EF, then AB = EF

2.) Name the property of equality that justifies the statement:
For any PQ, PQ=PQ.

3.) (1) All circles have diameters whose measure is twice the measure of the radius.

(2) AB is a radius of circle B.

Be careful of #2.
There are those who do not know standard notation.
Identity is probability what you need.
