Answer:
A two column proof is presented as follows;
Statement  Reason
                                     Reason
1. AB ║ DE, BD bisects AE         Given
    Given
2. ∠BAE = ∠AED, ∠ABD = ∠BDA  Alternate ∠s are equal
 Alternate ∠s are equal
3.   =

  By definition of bisection of line AE by BD
            By definition of bisection of line AE by BD
4. ΔABC ≅ ΔEDC   By SAA, rule of congruency
                         By SAA, rule of congruency
Step-by-step explanation:
Step 1. AB ║ DE, BD bisects AE         Given
    Given
Step 2. ∠BAE , ∠AED, and ∠ABD, ∠BDA  are pairs of alternate angles formed by the parallel lines, AB and DE and are therefore, equal
 are pairs of alternate angles formed by the parallel lines, AB and DE and are therefore, equal
Step 3.   =
 =   ,
 ,   =
 =   The bisection of line gives two lines of equal length. The bisection of AE by BD gives,
  The bisection of line gives two lines of equal length. The bisection of AE by BD gives,   and
 and   where
 where  =
 =   
 
Similarly, the bisection of BD by AE gives,  and
 and   , where
, where   =
 =  
Step 4. ΔABC ≅ ΔEDC   By the Side-Angle-Angle (SAA), rule of congruency, which states that two triangles having two angles and the corresponding non included sides of each triangle equal to the other, the two triangles are congruent.
