Question

eg and hj are parallel lines. which angles are alternate interior angles? ∠efi and ∠jif ∠efi and ∠jik ∠efi and ∠gfd ∠efi and ∠gfi

Explanation:

Alternate interior angles are formed when a transversal intersects two parallel lines. They are non - adjacent angles that lie between the two parallel lines and on opposite sides of the transversal. In the given figure with parallel lines $\overleftrightarrow{EG}$ and $\overleftrightarrow{HJ}$ and transversal $\overleftrightarrow{DK}$, $\angle EFI$ and $\angle JIF$ are non - adjacent, lie between the parallel lines and on opposite sides of the transversal.

Answer:

$\angle EFI$ and $\angle JIF$
