PLEASE HELP!!!!
3241004551 [841]

Answer: Correct

Step-by-step explanation:

The conclusion is valid. Since \overline{AB} \parallel \overline{DC} and \overline{AD} \parallel \overline{BC}, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since \overline{AB} \cong \overline{BC}, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.
