a parallelogram is a quadrilateral with four parallel sides. a trapezoid is a quadrilateral with two parallel sides.
A triangle
A shape with four non-parallel sides is an irregular quadrilateral. If the quadrilateral is bilaterally symmetrical, it is a deltoid (kite shape).
A quadrilateral in the shape of a kite has no parallel sides
A Trapezoid
quadrilateral
A quadrilateral is a shape with four sides. A parallelogram is a quadrilateral that has two pairs of parallel sides (i.e. the sides opposite each other are parallel). A rectangle, for example, is a parallelogram. A trapezoid, however, is an example of a quadrilateral that is not a parallelogram - it has four sides, but only two of them are parallel to each other.
A quadrilateral
A quadrilateral is any shape that has for sides. A trapezoid is any shape that has four sides AND exactly 2 sides that are parallel to each other.
a trapezoid has
There are quadrilaterals that have no parallel sides. (basically, a quadrilateral is just any enclosed shape with 4 sides) But all quadrilaterals have angles.
Any shape with four straight sides is a quadrilateral. A trapezoid has one pair of parallel sides, and a parallelogram has two pairs of parallel sides. So any shape with four straight sides and no parallel sides is a quadrilateral that is not a parallelogram or trapezoid.
