Question

other than itself, which angle is congruent to ∠aeb?

Explanation:

Step1: Recall vertical angles definition

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

Step2: Identify vertical angle of \(\angle AEB\)

When lines \(AB\) and \(CD\) intersect at point \(E\), \(\angle AEB\) and \(\angle DEC\) are vertical angles.

Answer:

\(\angle DEC\)
