Given: Seg AB ≅ SegCD
Seg B C ≅ Seg AD
Prove: ABCD is a parallelogram.
Segment AB congruent to Segment CD; Segment BC congruent to Segment AD
Segment AC congruent to Segment AC
Triangle ABC congruent to Triangle CDA
∠ B C A congruent to∠D A C ;∠B A C congruent to ∠ D C A
Segment B C parallel to Segment A D; Segment AB parallel to Segment DC
A B C D is a parallelogram
