Conditional converse inverse contrapositive worksheets Author: Wetagoyeme Bilocoto Subject: Conditional converse inverse contrapositive worksheets. If the converse is true, then the inverse is also logically true. Notice, the hypothesis \large{\color{blue}p} of the conditional statement becomes the conclusion of the converse. The student uses the process skills with deductive reasoning to understand geometric relationships. Kayegirl. LOGIC SYMBOLS Conjunction 1. is the conclusion. You should recognize this as the definition of an obtuse angle. When you’re given a conditional statement {\color{blue}p} \to {\color{red}q}, the inverse statement is created by negating both the hypothesis and conclusion of the original conditional statement.
