Question

4 lines are shown. A line with points A, F, D intersects with a line with points B, F, E at point F. A line extends from point F to point G between angle E F D. Another line extends from point F to point D in between angle B F D.
In the diagram, which angle is part of a linear pair and part of a vertical pair?

AngleBFC
AngleCFG
AngleGFD
AngleEFA

Answer 1

Angle EFA.

Reason: EFA and BFD are vertical angles (EF is opposite BF and FA is opposite FD), and EFA and EFD form a linear pair (they share ray EF and the nonshared rays FA and FD are opposite, making a straight line).
