Question

which angles are alternate interior angles?
∠bca and ∠bcf
∠gfc and ∠dca
∠dca and ∠efc
∠dcf and ∠efc

Explanation:

Alternate - interior angles are formed when a transversal intersects two lines. They are on the interior of the two lines and on opposite sides of the transversal. In the given figure, \(\angle DCF\) and \(\angle EFC\) are on the interior of the lines \(BD\) and \(EG\) and on opposite sides of the transversal \(AH\).

Answer:

\(\angle DCF\) and \(\angle EFC\)
