Question

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

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, if we assume the two vertical lines are parallel and the slanted line is a transversal, ∠BCF and ∠GFC are alternate - interior angles.

Answer:

∠BCF and ∠GFC
