Question

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

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 \(\angle CED\)

When lines \(AC\) and \(DB\) intersect at point \(E\), \(\angle CED\) and \(\angle AEB\) are vertical angles.

Answer:

\(\angle AEB\)
