Yes. A quadrilateral is any plane figure bounded by four straight lines. A parallelogram has both pairs of opposite sides parallel and is therefore a special kind of quadrilateral.
No. A quadrilateral is any four-sided figure. A trapezoid is one example of a quadrilateral.

Yes, the opposite angles of a quadrilateral inscribed in a circumscribed circle (cyclic quadrilateral) are always supplementary. This means that the sum of each pair of opposite angles equals 180 degrees. This property arises from the fact that the inscribed angles subtend the same arc, leading to their supplementary relationship. Thus, if one angle measures (x), the opposite angle will measure (180 - x).

True. In a quadrilateral inscribed in a circumscribed circle (cyclic quadrilateral), the adjacent angles are always supplementary, meaning their measures add up to 180 degrees. This property arises from the fact that opposite angles subtend arcs that sum to a semicircle. Thus, if one angle is known, its adjacent angle can be determined as 180 degrees minus the known angle.

A square, always, a rhombus, always, a parallelogram, always, and rectangles, always.
Yes, a parallelogram is always a quadrilateral. By definition, a parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length. Therefore, every parallelogram meets the criteria of being a quadrilateral.
