Based on the information in the diagram, can you prove that the figure is a parallelogram? Explain.
a. Yes; opposite sides are congruent.
b. Yes; opposite angles are congruent.
c. No; you cannot prove that the quadrilateral is a parallelogram.
d. Yes; two opposite sides are both parallel and congruent.

diagram: its a parallelogram, opposite sides and angles are congruent.
I drawn toward choice d because opposite sides and angle are congruent but answer key is not D its B.please help me why my answer D is incorrect.
