Question

eg and hj are parallel lines. which angles are adjacent angles? ∠hf and ∠ec ∠hf and ∠hc ∠hf and ∠gc ∠hf and ∠fc

Explanation:

Step1: Recall adjacent - angle definition

Adjacent angles share a common vertex and a common side.

Step2: Analyze angle pairs

Looking at the intersection of the lines, we check each pair.

Step3: Identify correct pair

$\angle HFI$ and $\angle IFJ$ share vertex $F$ and side $\overrightarrow{FI}$.

Answer:

$\angle HFI$ and $\angle IFJ$
