Required:

We need to classify angles 9 and 10.

Explanation:

Recall that the two angles are said to be adjacent angles when they share the common vertex and side.

The common vertex of angles 9 and 10 is B.

The common side of angles 9 and 10 is BD.

So angles 9 and 10 share the common vertex B and side BD.

Final answer:

Angles 9 and 10 are adjacent angles.
