Answer:
<AEB and <CED are congruent by vertical angles theorem.
Step-by-step explanation:
Given that AB and CD are parallel bro each other, and two straight lines intersect at E, therefore, <AEB and <CED that are formed are congruent to each other because they are vertical opposite angles.
Thus, the answer would be:
<AEB and <CED are congruent by vertical angles theorem.
