Angle AEB and CED are congruent by vertically theorem.
∠AEC and ∠BED are congruent by vertical theorem
How to find congruent angles?
The congruent angles of the figures can be found as follows;
AB is parallel to CD.
AB and CD are cut by two transversal lines that intersect.
Therefore,
AEB and CED are vertically opposite angles. Vertically opposite angles are congruent. This means they are congruent by vertical theorem.
Also ∠AEC and ∠BED are congruent by vertical theorem
