10 select all the angles that are adjacent to $angle 1$.
a $angle 6$
b $angle 5$
c $angle 3$
d $angle 4$
e $angle 1$
f $angle 2$

Explanation:

Adjacent angles share a common vertex and a common side, and do not overlap. ∠1 shares a vertex and side with ∠2 and ∠6, meeting the criteria for adjacent angles.
