what is the relationship between ∠a and ∠b?\nchoose 1 answer:\na vertical angles\nb complementary angles\nc supplementary angles\nd none of the above

Answer

Explanation:

Step1: Recall angle - relationship definitions

Vertical angles are opposite each other when two lines intersect. Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees.

Step2: Analyze ∠a and ∠b

∠a and ∠b form a linear - pair. A linear - pair of angles are adjacent angles whose non - common sides are opposite rays. The sum of angles in a linear - pair is 180 degrees.

Answer:

C. Supplementary angles
