Are all quadrilaterals parallelograms?
It is a quadrilateral but not a parallelogram since it does not have two pair of parallel sides. no, but all parallelograms are quadrilaterals. Quadrilateral means four sides, paralleograms means the sides are parallel. The only quadrilateral parallelograms are Square, rectangle, rhombus. * * * * * ... and parallelograms themselves: 2 pairs of parallel sides which are also equal.
Whigh quadrilatreal has one pair of parrel sides?
All parallelograms and trapezoids have at least one pairof parallel sides. The trapezoid has only one pair.
Are all rectangles parallelogram?
Yes. Parallelograms have two pairs of opposite sides that are parallel. Rectangles also have two pairs of opposite sides that are parallel, which makes them parallelograms.
Can you call a 4 sided shape a parallellogram?
Only if 2 sides are parallel with each other, and the other two sides are also parallel with each other. All squares are rectangles. All rectangles are parallelograms. All parallelograms are 4 sided. But not all 4-sided are parallelograms, not all parallelograms are rectangles, and not all rectangles are squares.
If a trapezoid is a parallelogram why is it?
Some people define trapezoids as having at least one pair of parallel sides. By this definition, all parallelograms are trapezoids, though not all trapezoids are parallelograms.Some people define trapezoids as having exactly one pair of parallel sides. By this definition, the terms "trapezoid" and "parallelogram" are mutually exclusive.
What 4 sided shape has 2 parrallel sides?
A square , a rectangle , a rhombus , in fact all the parallelograms have two parallel sides . Also a trapezium also has two parallel sides , which means one pair of parallel sides . The parallelograms have four parallel sides.

Is it true some rectangles are not parallelograms?
No. All rectangles are parallelograms, specifically those with two pair of parallel sides and all right angles.
Are All trapezoids are parallelograms?
No because a trapezoid has only 1 pair of parallel sides whereby a parallelogram has 2 pairs of parallel sides
Can all parallelograms be trapeziums?
No, because trapeziums (aka trapezoids) have only one pair of parallel sides, while parallelograms have two pairs.
Can any rectangles be parallelograms?
Yes, all rectangles can be considered parallelograms since they have opposite sides that are parallel to each other.
Whigh quadrilatreal has one pair of parrel sides?
All parallelograms and trapezoids have at least one pairof parallel sides. The trapezoid has only one pair.
Are parallelograms trapezoids?
There is disagreement among authors on this. It depends on your definition of a trapezoid. A parallelogram is defined as a quadrilateral with opposite sides parallel. A trapezoid is defined as either- a quadrilateral with at least one pair of parallel sides, or- a quadrilateral with exactly one pair of parallel sides.Therefore, if you go with the former definition, yes all parallelograms are trapezoids, because all parallelograms have at least one pair of parallel sides. If you use the latter definition, no.The "at least one" definition is consistent with the trapezoid's uses in higher math, such as the trapezoidal rule for approximating integrals.You can say, however, that all trapezoids are not parallelograms.
Do all quadrilaterals have opposite sides parallel?
No, only trapeziums (1 pair), parallelograms and squares (both pairs)
Is all quadrilaterals are parallelograms truth?
opposite sides are parallel opposite sides congruent opposite angles are equal opposite lines parallel 1 pair opp. lines parallel and congruent
Does a paraellelogram have four right angles and is a square?
A parallelogram does not need to have any right angles at all. It is a 4 sides figure with 2 pair of parallel sides, or you can define it as a quadrilateral with 2 pair of parallel sides. So a square certainly is a parallelogram, but most parallelograms are not squares. A rhombus, a rectangle, and a square are all types of parallelograms.
What is a quadralateral with exactly one pair of parallel sides?
it is a trapezoid. Quadralaterals can be groups according to how many pairs of parallel sides they have. A square and a rectangle have all 4 sides parallel since they are parallelograms and by definition a prallelogram has two sets of parallel sides. A kite has no parallel sides.
