Look at the parallelogram ABCD shown below:
(1st Image)
A parallelogram ABCD is drawn with BD as the diagonal. Angle ABD labeled angle 1. Angle CDB labeled angle 2. Angle CBD labeled

The table below shows the steps to prove that if the quadrilateral ABCD is a parallelogram, then its opposite sides are congruent:

Statement Reasons
1 AB is parallel to DC and AD is parallel to BC Definition of parallelogram
2 angle 1 = angle 2, angle 3 = angle 4 If two parallel lines are cut by a transversal
then the alternate interior angles are congruent
3 BD = BD Reflexive Property Reflexive Property
4 triangles ADB and CBD are congruent If two angles and the included side of a triangle are congruent to the corresponding angles and side of another triangle, then the triangles are congruent
5 AB = DC,
AD = BC Corresponding parts of _ are congruent
Which choice completes the missing information for reason 5 in the chart? (6 points)

Select one:
a. congruent parallelograms
b. congruent triangles
c. similar angles
d. similar triangles
