Answer:
Supplementary: A
Adjacent: B
Complementary: C
Vertical: D
Step-by-step explanation:
A is supplementary because they meet on a straight line, so they add to 180° deeming them to be supplementary angles.
B is adjacent since they share a side and a vertex, meaning they are next to each other, so they are adjacent angles.
C is complementary because they meet at two perpendicular lines, so it is a right angle, so they add up to 90° deeming them to be complementary angles.
D is vertical because they are vertically opposite angles.
