Hello,
In Basic Proportionality Theorem, we have not proved DBE and ECD congruent.
We have used the theorem of,
Triangles on the same base and between same parallel lines are equal in area.
Please check the theorem here https://www.teachoo.com/4284/1051/Theorem-6.1---Basic-Proportionality-Theorem-/category/Theorems/
