Question

eg and hj are parallel lines. which angles are vertical angles? ∠hik and ∠efd ∠hik and ∠gfd ∠hik and ∠gfi ∠hik and ∠jif

Explanation:

Vertical angles are formed when two lines intersect. They are opposite each other and are equal in measure. In the given diagram, the lines intersect at points \(I\) and \(F\). \(\angle HIK\) and \(\angle JIF\) are formed by the intersection of the trans - versal with the parallel lines and are opposite each other at the intersection point \(I\).

Answer:

\(\angle HIK\) and \(\angle JIF\)
