Example. Use the statement: Any two points are collinear. The converse would be If B then A or B -> A I told you it was easy. With the inverse, we negated the propositions. EXAMPLES Direct statement: If you drink Pepsi, then you are happy. The Converse, Inverse and Contrapositive. The mini-lesson targeted the fascinating concept of converse statement. To get the contrapositive, we must switch AND negate the propositions. 1) p → q 2) t → ~ w 3) ~ m → p 4) ~ p → ~ q. Definition of the Converse, contrapositive, and inverse of an implication Let P and Q be propositional variables. of p →q ¬q → ¬ p is the . In summary, the original statement is logically equivalent to the contrapositive, and the converse statement is logically equivalent to the inverse. The converse of the conditional statement is “If Q then P.” The contrapositive of the conditional statement is “If not Q then not P.” The inverse of the conditional statement is “If not P then not Q.” We will see how these statements work with an example. Example: Find the converse, inverse, and contrapositiveof “It raining is … So, by the law of contrapositive, the inverse and the converse also have the same truth value. p →q. * The converse … q →p is the . Note: As in the example, the contrapositive of any true proposition is also true. Examples Example 1. True/False Converse: _____True / … we can form new conditional statements . The inverse of a statement is taking the negation of each variable so with the last example we would have the original statement of: If A then B or A -> B The inverse would be If ~A then ~B or ~A -> ~B Contrapositive Improve your math knowledge with free questions in "Converses, inverses, and contrapositives" and thousands of other math skills. of p →q. of p →q ¬ p → ¬ q is the . Inverse. Index Prev Up Next Try these examples out: In 1 – 4, write the inverse of the statement in symbolic form. converse of proposition contrapositive of proposition Contents For the proposition P Q, the proposition Q P is called its converse, and the proposition Q P is called its contrapositive.. For example for the proposition "If it rains, then I get wet", At Cuemath, our team of math experts is dedicated to making learning fun for our favorite readers, the students! Fancy. Finally, we move on to the contrapositive. This packet will cover "if-then" statements, p and q notation, and conditional statements including contrapositive, inverse, converse, and biconditional. Example 7: Write four related conditional statements (if-then form, the converse, the inverse, and the contrapositive) of “ Guitar players are musicians.” Decide whether each statement is true or false. The following contrapositive statement is logically equivalent to the original if-then statement: "If I do not help you with your homework, then you will not do the dishes."
