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.
A conditional statement is true if, and only if, its contrapositive is true.
An example of a conditional statement is: If I throw this ball into the air, it will come down.In "if A then B", A is the antecedent, and B is the consequent.
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.
A conditional statement is indeed a statement that can be put in the form "if A, then B". The only time this conditional statement is false is when both A is true and also B is false.Read more: http://wiki.answers.com/What_is_a_conditional_statement#ixzz1lda5tB6E

The conjunction of a conditional statement and its converse is known as a biconditional statement. It states that the original statement and its converse are both true.
No. Consider the statement "If I'm alive, then I'm not dead." That statement is true. The converse is "If I'm not dead, then I'm alive.", which is also true.
It is a logical conditional statement which states that if some condition, a, is satisfied then another condition, b, must be satisfied. If a is not satisfied then we can say nothing about b.An equivalent statement, in a non-conditional form, is that~b or a must be TRUE, where ~b denotes not b.
