Answer:
False
Step-by-step explanation:
The definition of adjacent angles is two angles that share a common side and a common vertex. Also, they don't overlap
So in this case ∠1 and ∠2 share the common vertex A but do not share the common side, so these angles are not adjacent.
In this diagram, an example of adjacent angles would be ∠1 and ∠3.
Here's a visual example to understand what I meant
