Question

question 5 of 10
∠rdy and ∠nda are:
check all that apply.
a. complementary.
b. vertical angles.
c. supplementary.
d. a linear pair

Explanation:

Step1: Recall angle - pair definitions

Complementary angles add up to 90°. Vertical angles are opposite each other when two lines intersect. Supplementary angles add up to 180°. A linear pair is a pair of adjacent angles that form a straight - line (and are supplementary).

Step2: Analyze the given angles

\(\angle RDY\) and \(\angle NDA\) are opposite each other when the two lines \(RN\) and \(HY\) intersect at point \(D\).

Answer:

B. vertical angles
