CONVERSE, INVERSE, and CONTRAPOSITIVE of IF-THEN STATEMENTS GEO122 CONVERSE: “If p, then q” becomes “if q, then p.” INVERSE: “If p, then q” becomes “if not p, then not q.” CONTRAPOSITIVE: “If p, then q” becomes “if not q, then not p.” If it’s raining, then the field is wet. CONVERSE: If the field is wet, then it’s raining. INVERSE: If it’s NOT raining, then the field is NOT wet. CONTRAPOSITIVE: If the field is NOT wet, then it’s NOT raining.

CONVERSE, INVERSE, and CONTRAPOSITIVE of IF-THEN STATEMENTS GEO122 TRY IT! Answer on the next slide. Find the converse, inverse, and contrapositive of each if-then statement. 1. If it is Monday, then Julio is working. 2. If a pentagon is regular, then it is equiangular.

CONVERSE, INVERSE, and CONTRAPOSITIVE of IF-THEN STATEMENTS GEO122 ANSWERS! 1. If it is Monday, then Julio is working. CONVERSE: If Julio is working, then it is Monday. INVERSE: If it’s NOT Monday, then Julio is NOT working. CONTRAPOSITIVE: If Julio is NOT working, then it is NOT Monday. 2. If a pentagon is regular, then it is equiangular. CONVERSE: If a pentagon is equiangular, then it is regular. INVERSE: If a pentagon is NOT regular, the it is NOT equiangular. CONTRAPOSITIVE: If a pentagon is NOT equiangular, then it is NOT regular.
