The inverse of a conditional statement is a statement that negates the hypothesis $p$ and the conclusion $q$ of the conditional. An inverse statement can be written in if-then form.

This can be better understood with an example.

Conditional	$\text{If }\underset{p}{\underbrace{\text{a figure is a square}}},\text{then }\underset{q}{\underbrace{\text{it has four sides}}}.$	$p\Rightarrow q$
Inverse	$\text{If }\underset{\neg p}{\underbrace{\text{a figure is not a square}}},\text{then }\underset{\neg q}{\underbrace{\text{it does not have four sides}}}.$	$\neg p\Rightarrow \neg q$

By considering the truth table for a conditional statement, the conditions under which its inverse is true can be determined. The inverse of a conditional statement is false only when, in the original statement, the hypothesis is false and the conclusion is true. In any other case, the inverse of a conditional statement is true. The explanation for each row of the truth table is similar to the explanation for each row of the truth table for conditional statements.
