Which are vertical angles?
AFE and BFD
BFC and DFE
AFE and CFD
BFC and EFA

Answer: First option is correct.
Step-by-step explanation:
Vertically opposite angles are those angles which are opposite to each other when two lines are intersected at a point.
So, ∠AFE and ∠BFD are equal to each other as they are opposite to each other and line AD and BE are intersecting line at F.
i.e.∠AFE = ∠BFD
Hence, First option is correct.
