Answer:
Both SAS and AAS Congruence theorem
Explanation:
Congruent sides or angles are known to be equal in side length and angle. It does not really matter the plane on which they lay.
There are five Congruence theorem;
SSS, ASA, SAS, AAS and HL theorem.
In SSS, all the sides must be equal, While SAS, depicts equal consecutive S-A-S. HL is mainly applicable to right angle triangles only.
The triangles in the image shows two equal sides;
AC = EC and DC = BC , while the angle C are equal and between both sides.
