Depends on the quadrilateral. Eg in a cyclic Quad, opposite angles are supplementary. Note that it is impossible that there would be only one pair of supp. angles as the internal angles total 360o
All supplementary angles do not form a linear pair. The opposite angles of any quadrilateral inscribed in a circle (a cyclic quadrilateral) are supplementary but they are not a linear pair. However, all linear pair are supplementary.
A parallelogram.
Not necessarily. A linear pair of angles must be supplementary but supplementary angles need not form a linear pair. For example, the opposite angles of a cyclic quadrilateral are supplementary but they are (by definition) not next to one another.
Sometimes but not always depending on what type the 4 sided quadrilateral is.
Supplementary angles are any angles in which their degrees add to a sum of 180o. In the related links you will find an example of Supplementary angles.

No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
True
Supplementary
Then it's consecutive angles are supplementary.
True
True
How about a square or a rectangle
A parallelogram.
Any two angles whose measures add up to 180 degrees. For example, opposite angles of a cyclic quadrilateral (quadrilateral whose vertices are on a circle).
false
supplementary
