No. Every quadrilateral has 2 pairs of oposite sides. A paralelogram has two pairs of parallel sides. Cf wikipedia!
Yes. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.
Every quadrilateral has four sides and they are opposite each other. So, ALL quadrilaterals have both pairs of opposite sides.
Every quadrilateral has 2 pairs of opposite sides and so it is not clear what the question is about.
I would be seriously concerned if a quadrilateral had more than two pairs of opposite sides parallel! A quadrilateral with two pairs of opposite sides parallel is a parallelogram.
If both pairs of opposite sides are the same length, and both pairs of opposite angles are the same, the quadrilateral is a parallelogram (rhombus, rectangle, or square).
A paralellogram.
A quadrilateral with both pairs of opposite sides congruent is a parallelogram.

If a quadrilateral has two pairs of opposite congruent sides, then the quadrilateral is a parallelogram.
yesNot always!Parallelogram:A quadrilateral with both pairs of opposite sides parallel is called as a parallelogram.Rectangle:A quadrilateral with both pairs of opposite sides parallel and all the internal angles are 90o is called as a rectangle.Rectangles satisfy the condition of a parallelogram.So, all rectangles are always parallelogram.But, all parallelograms are not rectangles.Source: www.icoachmath.com
