Explain these laws: Law of Contrapositive

Law of Syllogism

Law of Detachment

1. In formulas: the contrapositive of is. . The law of contraposition says that a conditional statement is true if, and only if, its contrapositive is true. 2. In formulas: the contrapositive of is. . The law of contraposition says that a conditional statement is true if, and only if, its contrapositive is true. 3.If we call the first part p and the second part q then we know that p results in q. This means that if p is true then q will also be true. This is called the law of detachment and is noted: [(p→q)∧p]→q. The law of syllogism tells us that if p → q and q → r then p → r is also true.
