But I can try to give you some intuition...

Answer 16

First, a Conditional statement:
That's of the form "If ..., Then ... "

Answer 17

Answer 18

yea

Answer 19

So a conditional statement is something like:
If A, Then B
Now, the converse of that previous statement is:
If B, Then A
The Biconditional statement then combines both of these statements:
"A if and only if B"
