Statements:
AD = BC
AD || BC
Angles A and C are congruent
Angles B and D are congruent
Opposite sides are equal in length
Reasons:
Given
Given
If two lines are parallel, then the corresponding angles are congruent
If two lines are parallel, then the corresponding angles are congruent
If opposite angles of a quadrilateral are congruent, then the opposite sides are equal in length
Therefore, ABCD is a parallelogram.
