Question

consider the given figure.
from the figure, ∠cab and ∠bad are ______ angles.
a. vertical
b. supplementary
c. complementary
d. adjacent

Explanation:

Adjacent angles share a common vertex, a common side, and their non-common sides lie on opposite sides of the common side. In the figure, ∠CAB and ∠BAD share vertex A, common side AB, with AC and AD as non-common sides on either side of AB, fitting the definition of adjacent angles. Vertical angles are opposite each other, supplementary angles sum to 180°, and complementary angles sum to 90°, none of which apply here.

Answer:

D. adjacent
