Question

ce and fh are parallel lines. which angles are supplementary angles? ∠hgi and ∠edg ∠hgi and ∠fgd ∠hgi and ∠cdb ∠hgi and ∠fgi

Explanation:

Step1: Recall supplementary - angle definition

Two angles are supplementary if their sum is 180 degrees.

Step2: Analyze angle - relationships

$\angle HGI$ and $\angle FGD$ are a linear pair. A linear pair of angles are adjacent angles formed when two lines intersect. The sum of angles in a linear pair is 180 degrees.

Answer:

$\angle HGI$ and $\angle FGD$
