Is there enough information to prove ? If they are similar, which postulate tells you that they are? Explain which angles are congruent or which sides are proportional. This explanation is half of the credit for the problem.

to prove what? the triangles being similar?

if yes.  then yes there is enough info here...

campbell_st · Answer

The similarity proof is by all sides being in the same ratio 

$$\frac{ED}{AB} = \frac{CD}{CB}=\frac{CE}{AC} = \frac{1}{2}$$

the the corresponding angles are

angle D = angle B
Angle DEC = angle EAB
angle DCE = angle ABC
