Question

df and gi are parallel lines. which angles are supplementary angles? ∠feh and ∠ghe ∠feh and ∠fec ∠feh and ∠ihj ∠feh and ∠dec

Explanation:

Step1: Recall supplementary - angle definition

Two angles are supplementary if their sum is 180 degrees. Adjacent angles that form a straight - line are supplementary.

Step2: Analyze the given angles

$\angle FEH$ and $\angle FEC$ form a straight - line at point $E$. So, $\angle FEH+\angle FEC = 180^{\circ}$.

Answer:

$\angle FEH$ and $\angle FEC$
