Question

which angles pairs are vertical angles? choose all that apply. select all correct options. ∠bod & ∠aoc ∠cob & ∠coa ∠aod & ∠boc ∠bod & ∠a

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and have equal measures.

Step2: Analyze each pair

For the intersection of two lines, $\angle BOD$ and $\angle AOC$ are opposite each other, and $\angle AOD$ and $\angle BOC$ are opposite each other. $\angle COB$ and $\angle COA$ are adjacent angles, not vertical angles.

Answer:

$\angle BOD$ & $\angle AOC$, $\angle AOD$ & $\angle BOC$
