Question

other than itself, what is an angle that is congruent to \angle bfc?

Explanation:

Step1: Recall the definition of vertical angles

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

Step2: Identify vertical angle of ∠BFC

In the given diagram, when lines \(BC\) and \(DE\) (assuming appropriate line - like structures from the intersection at \(F\)) intersect at point \(F\), the angle opposite to \(\angle BFC\) is \(\angle DFE\).

Answer:

\(\angle DFE\)
