By using the AAA congruence property of Triangles, △aec≅△deb is proved 
It is given two triangles, Δaec and Δdeb, where e is the common point known as the midpoint of ad 
Also, it is given that, 
ca ║db 
We need to prove that, △aec≅△deb 
Then we'll use AAA congruence property of Triangles to prove the situation 
As ca ║db 
then, ∠cae = ∠ebd  (Alternate angles)
∠ace = ∠edb (Alternate angles)
and ∠aec = ∠deb (common angles)
Thus, by AAA congruence property, △aec≅△deb 
Hence, proved
