Sometimes, conditional relationships are true in both directions. It is true that the hypothesis causes the conclusion, but it may also be true that if the conclusion occurs first, then the hypothesis could result. That sort of reversal is called a converse.

Definition:
The converse of a conditional statement is created when the hypothesis and conclusion are reversed.

In other words, the events of the conditional statement are reversed.

Examples: 

Conditional statement: If three points lie on a line, then the three points are collinear
 

Hypothesis / p

Conclusion / q

Converse statement: If three points are collinear, then the three points lie on a line.
 

New Hypothesis / q

New Conclusion / p

Conditional statement: If it is an acute triangle, then all three interior angles have a measure less than 90°.
