Sticking a question mark at the end of a random phrase does not make a sensible question!

∙ 12y agoAbsolutely; a parallelogram is a form of quadrilateral, in that it has four sides. If the four sides come in two sets of parallel lines, you have a parallelogram.
The answer depends on the shape of the quadrilateral and the form in which that information is given: for example, lengths of sides and angles, coordinates of vertices.
A rectangle is a 4 sided quadrilateral having two pairs of parallel lines of different lengths
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.
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.
90 degrees
The word 'cyclic' is the adjective form of the noun cycle.
a quadrilateral where each angle is a right angle

A quadrilateral as described is a parallelogram. If the angles between the two sets of parallel lines are 90 degrees, the shape is a rectangle, a special form of parallelogram.
It is a kite whose diagonals are perpendicular to each other and form 4 right angles.
Yes, any quadrilateral can be used.
Yes and it will be in the form of an isosceles trapezoid which has one pair of opposite parallel sides of different lengths.
