Question

look at this diagram: if ce and fh are parallel lines and m∠hgi = 126°, what is m∠edg?

Explanation:

Step1: Identify angle - relationship

$\angle HGI$ and $\angle EDG$ are corresponding angles.

Step2: Apply property of parallel lines

For parallel lines $CE$ and $FH$, corresponding angles are equal. So $m\angle EDG=m\angle HGI$.

Answer:

$126$
