Some are, and some are not. A parallelogram is a special kind of quadrilateral ... one in which every side is parallel to the one across from it. So all parallelograms are quadrilaterals, but there are also a lot of other quadrilaterals that are not parallelograms.
Parallelograms!
No but they are all quadrilaterals
They are quadrilaterals; opposite sides are parallel.
Quadrilaterals do not bisect each other. They could in special cases. In parallelograms (types of quadrilaterals), the diagonals bisect each other.
All parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms
All 4 sided parallelograms are quadrilaterals.
All 4 sided parallelograms are quadrilaterals.
Not necessarily. All parallelograms are quadrilaterals but not all quadrilaterals are parallelograms. Parallelograms are more specific instances of quadrilaterals. Its like saying all squares are rectangles but not all rectangles are squares.

Yes all parallelograms are 4 sided quadrilaterals.
All parallelograms are in the class of 4 sided quadrilaterals.
parallelograms and,or quadrilaterals
Parallelograms are a special form of quadrilaterals (four sided polygons). Parallelograms have 2 sets of parallel sides. So you could say that all parallelograms are quadrilaterals. Or you could say that all parallelograms are polygons. I'm not sure what you are asking.
Parallelograms!
no, but all parallelograms are quadralaterals.
No, all quadrilaterals are not parallelograms.
