Question

which angle is a vertical angle with ∠efd? ∠dfb ∠ced ∠afb ∠bfc

Explanation:

Step1: Recall vertical angles definition

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

Step2: Analyze each option

• $\angle DFB$: Not opposite $\angle EFD$.
• $\angle CED$: Not formed by the intersection with $\angle EFD$'s lines.
• $\angle AFB$: Opposite $\angle EFD$ as they are formed by the intersection of two lines.
• $\angle BFC$: Not opposite $\angle EFD$.

Answer:

$\angle AFB$
