Question

Which are vertical angles?

AFE and BFD
BFC and DFE
AFE and CFD
BFC and EFA

Answer 1

Your answer is A, because a verticle angle is made with two intersecting lines

Answer 2

Answer: First option is correct.

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.
