A conditional statement is true if, and only if, its contrapositive is true.
not b not a its contrapositive
A Contrapositive statement is logically equivalent.
always true
Look at the statement If 9 is an odd number, then 9 is divisible by 2. The first part is true and second part is false so logically the statement is false. The contrapositive is: If 9 is not divisible by 2, then 9 is not an odd number. The first part is true, the second part is false so the statement is true. Now the converse of the contrapositive If 9 is not an odd number, then 9 is not divisible by two. The first part is false and the second part is true so it is false. The original statement is if p then q,the contrapositive is if not q then not p and the converse of that is if not p then not q
A conditional statement is true if, and only if, its contrapositive is true.
If a conditional statement is true then its contra-positive is also true.
If a conditional statement is true, then so is its contrapositive. (And if its contrapositive is not true, then the statement is not true).
by switching the truth values of the hypothesis and conclusion, it is called the contrapositive of the original statement. The contrapositive of a true conditional statement will also be true, while the contrapositive of a false conditional statement will also be false.
not b not a its contrapositive
false
true
The inverse of a conditional statement switches the hypothesis and conclusion. The converse of a conditional statement switches the hypothesis and conclusion. The contrapositive of a conditional statement switches and negates the hypothesis and conclusion.
A Contrapositive statement is logically equivalent.
