Question

which angle number represents an angle vertical to ∠ehd?

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 and vertical angles

Lines $CD$ and $EF$ intersect at point $H$. $\angle EHD$ and $\angle FHC$ are vertical angles. In the given number - ing of angles, $\angle 4$ is $\angle FHC$.

Answer:

$\angle 4$
