Question

bd and eg are parallel lines. which angles are corresponding angles? ∠bca and ∠efc ∠bca and ∠bcf

Explanation:

Step1: Recall corresponding - angles definition

Corresponding angles are formed when a transversal intersects two parallel lines. They are in the same relative position at each intersection.

Step2: Analyze the given angles

For parallel lines $\overleftrightarrow{BD}$ and $\overleftrightarrow{EG}$ with transversal $\overleftrightarrow{HA}$, $\angle BCA$ and $\angle EFC$ are in the same relative position (above the parallel lines and to the right of the transversal). $\angle BCA$ and $\angle BCF$ are adjacent - angles (not corresponding).

Answer:

$\angle BCA$ and $\angle EFC$
