Not necessarily. If the statement is "All rectangles are polygons", the converse is "All polygons are rectangles." This converse is not true.
No, the converse of the statement "If I am hungry then I am not happy" is "If I am not happy then I am hungry." While the original statement is assumed to be true, its converse does not necessarily follow that truth. The truth of the original statement does not guarantee the truth of its converse; there could be other reasons for not being happy that do not involve hunger.
true
Yes
The statement is false. The conditional statement "If P, then Q" and its converse "If Q, then P" are distinct statements, but the negation of the converse would be "It is not the case that if Q, then P." Thus, the conditional and the negation of the converse are not equivalent or directly related.
This is not always 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.
Proof by Converse is a logical fallacy where one asserts that if the converse of a statement is true, then the original statement must also be true. However, this is not always the case as the converse of a statement may not always hold true even if the original statement is true. It is important to avoid this error in logical reasoning.
Statement: All birds lay eggs. Converse: All animals that lay eggs are birds. Statement is true but the converse statement is not true. Statement: If line A is perpendicular to line B and also to line C, then line B is parallel to line C. Converse: If line A is perpendicular to line B and line B is parallel to line C, then line A is also perpendicular to line C. Statement is true and also converse of statement is true. Statement: If a solid bar A attracts a non-magnet B, then A must be a magnet. Converse: If a magnet A attracts a solid bar B, then B must be non-magnet. Statement is true but converse is not true (oppposite poles of magnets attract).
A biconditional is the conjunction of a conditional statement and its converse.

No, the converse of the statement "If I am hungry then I am not happy" is "If I am not happy then I am hungry." While the original statement is assumed to be true, its converse does not necessarily follow that truth. The truth of the original statement does not guarantee the truth of its converse; there could be other reasons for not being happy that do not involve hunger.
A conditional statement is true if, and only if, its contrapositive is true.
No, the converse of a statement does not necessarily have to be true. In this case, the original statement "If you are hungry then you are not happy" does not imply that its converse "If you are not happy then you must be hungry" is always true. It is possible to be unhappy for reasons other than hunger.
The Answer: NO
true
