Question

∠rdy and ∠nda are. check all that apply. supplementary complementary vertical angles a linear pair

Explanation:

Step1: Recall angle - relationship definitions

Supplementary angles add up to 180°. Complementary angles add up to 90°. Vertical angles are non - adjacent angles formed by two intersecting lines. A linear pair is a pair of adjacent angles whose non - common sides are opposite rays and they add up to 180°.

Step2: Analyze the given angles

Since the two lines are perpendicular, \(\angle RDY = 90^{\circ}\) and \(\angle NDA=90^{\circ}\). \(\angle RDY\) and \(\angle NDA\) are non - adjacent and are formed by two intersecting lines. They are vertical angles. Also, \(\angle RDY+\angle NDA = 90^{\circ}+90^{\circ}=180^{\circ}\), so they are supplementary.

Answer:

Supplementary, vertical angles
