Question

df and gi are parallel lines. which angles are vertical angles? ∠fec and ∠deh ∠fec and ∠ghe ∠fec and ∠feh ∠fec and ∠ghj

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent.

Step2: Analyze the intersection at point E

The lines \(JC\) and \(DF\) intersect at point \(E\). \(\angle FEC\) and \(\angle DEH\) are opposite each other at the intersection of these two lines.

Answer:

\(\angle FEC\) and \(\angle DEH\)
