To determine whether angles 1 and 2 are adjacent, consider the definition of adjacent angles: they are two angles that share a common side and a common vertex but do not overlap.
Since I can't see the diagram you are referring to, I cannot definitively answer if the statement is true or false.
However, if angles 1 and 2 share a side and vertex without overlapping, then the answer would be True. If they do not meet that criteria, the answer would be False.
Please provide more information or a description of the angles for a precise answer!
