Answer:
ASA
Step-by-step explanation:
Angle BAC and angle CDE are congruent ( indicated by a single dashed dashed line on the angle )
Side AC and side DC are congruent ( also indicated by a single dashed line )
Angle DCE and angle BCA are congruent ( this is because they are vertical angles and vertical angles are congruent )
Hence, the two triangles are congruent because of the congruency statement ASA
( angle. side, angle )
