The converse of the given statement is which of the following? so how do you know? If a quadrilateral is not a rectangle, then it does not have two pairs of parallel sides. Use an inquisitive resource to find the truth of related statements. To save time, I have combined all the truth tables of a conditional statement, and its converse, inverse, and contrapositive into a single table. contrapositive 11. I have the starting card and then give a card to each student. Use an inquisitive resource to find the truth of related statements. Then think about something that does have conditions.
