Bi-Conditional Statement

A statement written in "if and only if" form.

    It is sunny if and only if we are in Arizona.

A true bi-conditional statement means the conditional statement AND the converse are both TRUE!

    x = 3 if and only if x2 = 9

       1. Conditional Statement: If x = 3 then x2 = 9.

           This is true!

       2. Converse: If x2 = 9, then x = 3

           This is FALSE! x = 3 AND -3
