Answer

not reversible

Work Step by Step

Reversing a statement is similar to writing the converse of a conditional in that you switch the phrases at the start and end of the statement. Two angles that are adjacent form a linear pair. The given statement is not reversible, because the reversed statement is false. Adjacent angles form a linear pair only if the sum of their measures is 180.
