Proved below.

Step-by-step explanation:

Given:  

As shown in the figure, let in Δ ABC, D is midpoint of AB and DE is parallel to BC.

∴ AD = DB

To prove:  

AE = EC

Proof:  

Since,D║BC

∴ By Basic Proportionality Theorem,

\frac{AD}{DB}=\frac{AE}{EC}

Since, AD = DB          [given]

\frac{AE}{EC}=1  

∴ AE = EC

Hence proved.
