Answer:
Step-by-step explanation:
As we know E is the mid point of AB so,
AE = BE
As all sides of a square are equal so,
AD = BC
And as all angles of a square measure 90o so
Angle A = Angle B
Thus,By SAS congruence criterion Triangle AED and BEC are congruent
therefore,ED = EC by CPCT (Coresponding Parts of Congruent Triangles)
