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.
Yes, in a parallelogram, each pair of consecutive angles is supplementary, meaning that they add up to 180 degrees. This property arises because the opposite angles are equal, and the sum of angles in any quadrilateral is 360 degrees. Therefore, if two angles are consecutive, the other two angles must also be supplementary to maintain this total.

No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
True
Supplementary
Then it's consecutive angles are supplementary.
True
True
A parallelogram.
How about a square or a rectangle
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).
