To determine what conclusions can be made about the given parallelogram, we need to consider the properties of rhombuses and rectangles.

A rhombus is a parallelogram with all sides of equal length. Therefore, if the parallelogram is not a rhombus, it means that at least one pair of its opposite sides is not of equal length.

A rectangle, on the other hand, is a parallelogram with all angles measuring 90 degrees. So, if the parallelogram is not a rectangle, it means that at least one angle is not 90 degrees.

With these considerations, we can conclude the following about the parallelogram:

1. The opposite sides may or may not be of equal length.
2. The angles may or may not measure 90 degrees.

In summary, if the given parallelogram is not a rhombus or a rectangle, there are no specific conclusions that can be made about its side lengths or angles.
