It's C, the diagonals are not congruent (they aren't equal) and with rectangles they always have to be.

Answer:

(c) No, it is not a rectangle because the diagonals are not congruent

Explanation:

The diagonals of a rectangle bisect each other and are the same length. The lengths of the diagonals of this figure are ...

AC = √((8-0)² +(6-2)²) = √(64+16) = 4√5

BD = √((5-3)² +(2-6)²) = √(4 +16) = 2√5

The diagonals are different lengths, so the parallelogram is not a rectangle. This is described correctly in choice C:

No, it is not a rectangle because the diagonals are not congruent.

_____

The lengths are found using the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)
