Not necessarily. A quadrilateral is a plane shape with four straight sides. There is no requirement for a side to be parallel to another.

Are all quadrilaterals parrallelograms?
No, and all parrallelograms are not quadralaterals.
Are all trapezoids parrallelograms?
No but they are all 4 sided quadrilaterals
Which two shapes are not parrallelograms and why?
A circle and an ellipse. Neither of them are polygons and so cannot be quadrilaterals, still less parallelograms.
Are rectangles special parrallelograms?
Yes, except that the word is parallelogram.
Are parrallelograms angles always congruent?
Opposite angles are congruent in a parallelogram.
Are all quadrilaterals parrallelograms?
No, and all parrallelograms are not quadralaterals.
Is all parrallelograms are quadrilaterals?
All parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms
Are all trapezoids parrallelograms?
No but they are all 4 sided quadrilaterals
Which two shapes are not parrallelograms and why?
A circle and an ellipse. Neither of them are polygons and so cannot be quadrilaterals, still less parallelograms.
Which two parrallelograms match the qualities of a square?
it is a gogo
Are rectangles special parrallelograms?
Yes, except that the word is parallelogram.
All parrallelograms are squares?
No, the other way. All squares are parallelograms.
Are parrallelograms angles always congruent?
Opposite angles are congruent in a parallelogram.
Are all kites quadrilaterals?
All kites are quadrilaterals, but quadrilaterals are not kites.
Are all squares similar to quadrilaterals?
All squares are quadrilaterals. Not all quadrilaterals are squares.
What is the formula to find volume of a quadrilaterals?
what a quadrilaterals
What are fifteen or more facts and features relevant to geometrical quadrilaterals?
You're supposed to ask only one question at a time but here we go for 15 or more questions about quadrilaterals:- 1 Quadrilaterals are 4 sided 2 dimensional polygons 2 Quadrilaterals have 4 interior angles that add up to 360 degrees 3 Quadrilaterals have 4 exterior angles adding to 360 degrees 4 Quadrilaterals have 2 diagonals 5 Quadrilaterals have a perimeter which is the sum of their 4 sides 6 Quadrilaterals have areas with formulae depending on their types 7 Quadrilaterals can individually tessellate 8 Quadrilaterals can be split into 2 triangles 9 Quadrilaterals can be squares 10 Quadrilaterals can be rectangles 11 Quadrilaterals can be parallelograms 12 Quadrilaterals can be rhombuses 13 Quadrilaterals can be trapezoids or trapeziums 14 Quadrilaterals are sometimes isosceles trapezoids 15 Quadrilaterals can look like kites 16 Quadrilaterals can undergo transformations on the Cartesian plane 17 Quadrilaterals are congruent or similar when identical in angles and shapes 18 Quadrilaterals can form the cross-section of prisms 19 Quadrilaterals sometimes have lines of symmetry 20 Quadrilaterals have certain properties within a circle 21 Quadrilaterals can be subjected to trigonometry QED by David Gambell
