Question

look at this diagram: if df and gi are parallel lines and m∠ghe = 125°, what is m∠ihj?

Explanation:

Step1: Identify vertical - angle relationship

$\angle GHE$ and $\angle IHJ$ are vertical angles.

Step2: Apply vertical - angle property

Vertical angles are congruent. So $m\angle IHJ=m\angle GHE$.

Answer:

$125$
