## 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 x^{2} = 9

1. Conditional Statement: If x = 3 then x^{2} = 9.

This is true!

2. Converse: If x^{2} = 9, then x = 3

This is FALSE! x = 3 AND -3
