Question

bd and eg are parallel lines. which angles are alternate interior angles? ∠gfc and ∠efh ∠gfc and ∠bcf ∠gfc and ∠dca ∠gfc and ∠bca

Explanation:

Step1: Recall definition of alternate - interior angles

Alternate - interior angles are formed when a transversal intersects two parallel lines. They are non - adjacent angles between the two parallel lines and on opposite sides of the transversal.

Step2: Analyze the given angles and parallel lines

Lines $\overleftrightarrow{BD}$ and $\overleftrightarrow{EG}$ are parallel. The transversal is $\overleftrightarrow{HA}$. $\angle GFC$ and $\angle BCA$ are non - adjacent, between the parallel lines $\overleftrightarrow{BD}$ and $\overleftrightarrow{EG}$, and on opposite sides of the transversal $\overleftrightarrow{HA}$.

Answer:

$\angle GFC$ and $\angle BCA$
