None. The only common property of quadrilaterals is that they are plane figures that are bounded by four straight sides, and that they have four vertices. So far all quadrilaterals are candidates for the answer. But then with each quadrilateral you get some unique property that is not shared by others so NO quadrilateral has all te properties of all the other quadrilaterals.
A quadrilateral having both pairs of opposite sides parallel to each other.
Every quadrilateral has four sides and they are opposite each other. So, ALL quadrilaterals have both pairs of opposite sides.
a polygon,quadrilateral,parallelogram,rectangle and a rhombus hope this helps if you are having a problem with math
True

They must meet at right angles and only one of them must bisect the other. (if both bisect one another, the quadrilateral will be a square).

A rectangle.
A quadrilateral having both pairs of opposite sides parallel to each other.
Quadrilaterals usually have special names only if they DO have parallel sides, or some other special property. You might just call it "quadrilateral", or "a quadrilateral with no parallel sides".
Every quadrilateral has four sides and they are opposite each other. So, ALL quadrilaterals have both pairs of opposite sides.
Quadrilateral can certainly be parallelograms, but they can also be squares, rectangles, and other 4-sided shapes.All parallelograms are quadrilaterals but not all quadrilaterals are parallelograms.
