What is the converse of the linear pairs theorem

The converse of a logicalstatement is a s tatement formed by reversing the parts of the statement.

For example, the logical statement "A implies B" has a converse of "B implies A"

The linear pairs theorem states that "if two angles form a linear pair, then they are supplementary".

The converse of the linear pairs theorem is therefore, "if two angles are suplementary, then they form a linear pair".
