A quadrilateral has four sides & no other special properties.
Any given side has two adjacent sides and one opposite side. There are two pairs of opposite sides.
A parallelogram is a quadrilateral where both pairs of opposite sides are parallel to each other.
Rectangles (including squares) are parallelograms.
Rhombi (including squares) are parallelograms.
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.
Yes because all parallelograms have four sides. But the opposite is not true. There are some quadrilaterals that aren't parallelograms.
Parallelograms!
No but they are all quadrilaterals
They are quadrilaterals; opposite sides are parallel.
All parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms

All 4 sided parallelograms are quadrilaterals.
All 4 sided parallelograms are quadrilaterals.
rectangles,rhombus,and a square
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 because all parallelograms have four sides. But the opposite is not true. There are some quadrilaterals that aren't parallelograms.
yes; all trapeziums are quadrilaterals
Yes.
They are quadrilaterals which have two pairs of parallel sides.
