There are quadrilaterals that have no parallel sides. (basically, a quadrilateral is just any enclosed shape with 4 sides) But all quadrilaterals have angles.

What thirteen letter shape has 2 pairs of parallel sides 4 right angles but sides are not all the same length?
The geometric answer is a rectangle but that does not have 13 letters. The answer is NOT a quadrilateral nor parallelogram because neither of them need have 4 right angles.
Is a quadrilateral also a parallelogram?
It may be. A quadrilateral has four sides, but they need not be all the same length, nor parallel to each other. It's true that a parallelogram *is* a quadrilateral.
Is a quadrilateral with one right angle necessarily a rectangle?
A quadrilateral can have two right angles and still not be a rectangle, if one side is oblique (neither right nor parallel) to the others, but three right angles force the fourth, and you have a rectangle.
Does a circle have 4 sides?
NO! DEFINITELY NOT!!! A circle has NO sides at all! A quadrilateral has four sides. A quadrilateral is a polygon with four sides. For example: the square, the rhombus, the rectangle etc.. A circle measures 360 centimetres in circumference. This so because there has to be some way to measure the circle, and mathematicians came up with this strategy, I don't know how (yet). The point is the circle cannot have sides or angles because it is completely round, and a round figure cannot have sides nor angles.
What is a polygon with 4 sides none of which is the same length?
An irregular QUADRILATERALOrAn irregular QUADRANGLE(closed figures in Euclidean space have the same number of edges (sides) and angles ).Note:In American (and some other, but not European English usage) Trapezium is a general (or irregular) quadrilateral (no parallel edges or edges necessarily of equal length nor therefore any requirements on equal angles) A Trapezoid in the US has two parallel edges and thus complementary angles at the ends of the non-parallel edges.The trapezoid and trapezium both might have up to 3 sides of the same length since the term trapezoid only is used to describe the number of parallel edges and the term trapeziumonly to describe the number of edges (and necessarily the number of angles).

Is a four sided shape called a parallelogram?
Only if both pairs of opposite sides are parallel! Any four sided shape is a tetragon, also a quadrilateral; these have no constraints other than they be planar (all vertexes lie in the same plane); the sides need not be parallel nor any angles equal (often a quadrilateral should not be self-intersecting)

Is a octagon a quadrilateral and a parallelogram?
An octagon is neither a quadrilateral nor a parallelogram. "Quadrilateral" refers to a shape that has four sides. "Parallelogram" refers to a shape that has two pairs of opposite, congruent sides. An octagon has eight sides, and since eight is not equal to four, an octagon is neither a quadrilateral nor a parallelogram.
What are the consecutive sides of a quadrilateral?
The only thing that can be said about consecutive sides of a quadrilateral is that they meet at a vertex. There is no restriction on the angle, nor on their respective lengths.

Do parallelograms have parallel sides?
Yes. A Parallelogram is a quadrilateral that has two pairs of parallel sides which are opposite each other and of equal length, though the pairs may be of different length to each other. If the angles are all 90° then the parallelogram is also a rectangle. If the angles are all 90° AND all sides are equal then the parallelogram is also a square. All squares are rectangles, but not all rectangles are squares; Similarly all squares are rhombuses but not all rhombuses are squares And all rhombuses, and thus squares, are parallelograms, but not all parallelograms are rhombuses (nor squares).
What polygon with 4 sides and none of which are the same length?
A quadrilateral is the term for a four sided polygon. It is the most general term. It does not imply anything about side lengths or angles being equal nor unequal. Some other answerers have stated that a trapezium (or trapezoid, depending or where you live) fits this description, but it is possible to have two sides (the non parallel sides) to have the same length and still be a trapezoid. But you can have a trapezoid (which only needs 4 sides and 1 pair of parallel sides) that fits the description above (4 sides none of which are equal length).
Opposite sides not parallelangles not equal?
A quadrilateral that is not a parallelogram, not a trapezoid nor a rhombus. It is not a square nor a rectangle. There ought to be a name for this! /Brian W
What is a parallelogram with 2 congruent sides and two congruent angles?
A parallelogram cannot have only two congruent sides, nor only two congruent angles.
