Question

which angles are vertical to ∠bec? select all that apply. ∠ced ∠dea ∠bea ∠aeb

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent.

Step2: Identify intersecting lines

Lines $AB$ and $CD$ intersect at point $E$.

Step3: Determine vertical angles to $\angle BEC$

The angle opposite $\angle BEC$ is $\angle DEA$.

Answer:

$\angle DEA$
