A parallelogram has vertices upper A, upper B, upper C, and upper D. Opposite vertices are connected via diagonal lines that intersect at an interior point labeled upper E. Sides upper A upper D and upper B upper C are much longer than the other sides.

is a parallelogram, what would need to be true about EB
and ED
?

To prove that quadrilateral ABCD is a parallelogram using the diagonals that intersect at point E, you would need to demonstrate that the segments formed by the intersection point E on the diagonals are proportional.
In a parallelogram, the diagonals bisect each other, which means that:
\[ EB = ED \]
This implies that the lengths of segments EB and ED must be equal.
Therefore, the correct response is:
EB must be the same length as ED.
