The relationship between ∠BFA and ∠CFD is vertical angles. option D
What is the relationship between ∠BFA and ∠CFD?
A vertical angles or vertically opposite angles can be defined as the angles that lie opposite to each other when two lines intersect. Vertical angles are equal.
When line BD intersect line AC
∠AFD and ∠BFC are vertically opposite and equal
Therefore,
∠BFA and ∠CFD are vertically opposite and equal.
