A 4-sided polygon with four or three sides of different lengths can readily be constructed so that no two sides are parallel. The shapes so obtained will not have an axis of symmetry.
However, a kite is a quadrilateral having two pairs of adjacent sides of equal length but does not have any parallel sides. It is symmetrical about its long axis.
A square is a four-sided polygon with two congruent parallel sides.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
NO!!!! A parallelogram is a polygon of four sides. The opposite sides are parallel and equal in length.
Some types of quadrilaterals don't have parallel sides. Such as a diamond or a kite.
That would have to be a trapezoid
A square is a four-sided polygon with two congruent parallel sides.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
Any polygon with four or more sides can have parallel sides.
quadrilateral
A four-sided polygon with opposite sides parallel could be a square, a rectangle, or a rhombus.If it has one pair of opposite, parallel sides, then it is a trapezoid. If it has two pairs of opposite, parallel sides, then it is a parallelogram.
NO!!!! A parallelogram is a polygon of four sides. The opposite sides are parallel and equal in length.
Some types of quadrilaterals don't have parallel sides. Such as a diamond or a kite.
A right trapezoid is a four-sided polygon with two right angles and two parallel sides.
That would have to be a trapezoid
General term for a polygon with 4 sides is a quadrilateral. A parallelogram is the special case with two pairs of parallel sides.
The parallel sides of a polygon are sides that are segments of parallel lines. A polygon need not have any parallel lines. A triangle, for example, is a polygon that cannot have parallel lines.
A shape with four non-parallel sides is an irregular quadrilateral. If the quadrilateral is bilaterally symmetrical, it is a deltoid (kite shape).
