Answer:
Step-by-step explanation:
Pay attention to order of vertices when comparing the congruent parts or figures.
C and D as well as B and E are corresponding vertices according to angle marks and side marks.
So if <AED =100 degrees result <BEC = 100 degrees too and 360-200=160
so 160/2 = 80 what mean that angle DEC=80 degrees
