statement that uses if and only if. it can only be accurate if the conditional and converse are correct. Biconditional statement
if p-q is true, and if p is true, then q is true. Law of Detachment

If a=b, then a+c=b+c Addition property of equality
If a=b, then a divided by c = b divided by c Division property of equality
For any real #, a=a Reflexive property of equality
