A statement true in its original and converse rewritten in “if and only if” form

if and only hmmm i think it should be if the acute did this then it can only do this like that.
an "if, then" statement is conditional
"if and only if" means the statement is true in either direction (biconditional).
For example: She is pretty if and only if she is smart
means
If she is pretty, then she is smart. AND If she is smart, then she is pretty.
Answer: biconditional statement
