There are quadrilaterals that have no parallel sides. (basically, a quadrilateral is just any enclosed shape with 4 sides) But all quadrilaterals have angles.
Circle? -- any shape without sides . . . circle, ellipse, etc. -- any triangle -- any quadrilateral except trapezium and parallelogram -- any regular polygon with an odd number of sides
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.
Yes
No. A trapezoid must have one pair of parallel sides, and a parallelogram must have two pair.But a quadrilateral in general doesn't necessarily have any parallel sides.

A paralellogram.
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.
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.
Yes
No. A trapezoid must have one pair of parallel sides, and a parallelogram must have two pair.But a quadrilateral in general doesn't necessarily have any parallel sides.
Any four-sided shape is a Quadrilateral. Square, Rectangle, Parallelogram, rhombus, trapezoid etc. It may have no parallel sides as in a kite, 1 parallel side as in trapezoid or 2 parallel sides as in parallelogram.
Any quadrilateral with two sets of parallel sides is called a parallelogram.
No. A trapezoid is defined as a quadrilateral with two parallel sides. Therefore, the quality of quadrilateral is necessary, and this condition is satisfied. ... Any other shape can have four sides, but if it does not have (at least) two parallel sides, it cannot be a trapezoid.
A quadrilateral is any figure with 4 sides. ("quad" = 4, "latus" = side). It doesn't have to have any parallel lines. If it happens to have two sides that are parallel, then it's a trapezoid. If it happens to have two pairs of parallel sides, then it's a parallelogram. Common parallelograms are rectangles, squares, and kites.
All parallelograms are quadrilaterals. Not all quadrilaterals are parallelograms. A quadrilateral refers to any polygon with four sides. A parallelogram refers to any quadrilateral with two pairs of parallel sides.
