If p->q, then the law of the contrapositive is that not q -> not p
The word contrapositive is a noun. The plural noun is contrapositives.
If a conditional statement is true, then so is its contrapositive. (And if its contrapositive is not true, then the statement is not true).
The converse of an inverse is the contrapositive, which is logically equivalent to the original conditional.
The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
A contrapositive means that if a statement is true, than the characteristics also pertains to the other variable as well.
If a figure is not a triangle then it does not have three sides ,is the contrapositive of the statement given in the question.
if the statement is : if p then q converse: if q then p inverse: if not p then not q contrapositive: if not q then not
The contrapositive of the statement "All journalists are pessimists" is "If someone is not a pessimist, then they are not a journalist." This reformulation maintains the same truth value as the original statement, meaning that if the original statement is true, the contrapositive is also true.
The statement "All red objects have color" can be expressed as " If an object is red, it has a color. The contrapositive is "If an object does not have color, then it is not red."
"contrapositive" refers to negating the terms of a statement and reversing the direction of inference. It is used in proofs. An example makes it easier to understand: "if A is an integer, then it is a rational number". The contrapositive would be "if A is not a rational number, then it cannot be an integer". The general form, then, given "if A, then B", is "if not B, then not A". Proving the contrapositive generally proves the original statement as well.
The law of contrapositive states that a conditional statement of the form "If P, then Q" (P → Q) is logically equivalent to its contrapositive, "If not Q, then not P" (¬Q → ¬P). This means that if the original statement is true, the contrapositive must also be true, and vice versa. This principle is widely used in mathematical proofs and logical reasoning to demonstrate the validity of arguments.
