Answer :

Final answer:

Without the measures for angles 9 and 16, we can't definitively classify them. However, the terms supplemental, complimentary, vertical, and adjacent refer to angles, and their definitions have been provided for clarity.

Explanation:

In order to classify the pair of angles, we'll need more information about their specific measures or a diagram. Anyway, let's define these terms for clarity:

1. Supplementary angles: These are two angles whose measures add up to 180 degrees.

2. Complementary angles: In this case, the two angles measure up to 90 degrees when summed up.

3. Vertical angles: These angles are opposite each other when two lines intersect. They are always equal.

4. Adjacent angles: These are two coplanar angles with a common side and a common vertex but no common interior points.

If you have the measures of angles 9 and 16, you can determine which category they fit into using these definitions.
