Four line segments can always form a quadrilateral, as long as none of them is longer than the sum of the lengths of the other three,
A quadrilateral.
No, a circle can't be a parallelogram. A circle is a curve. A parallelogram is a quadrilateral with two pairs of parallel sides constructed with four line segments. The line segments are straight, and the circle is a continuous curve.
It is a closed plane figure bounded by four straight line segments.

A quadrilateral has 4 line segments
US DefinitionA trapezoid is a closed plane figure consisting of four line segments/sides; two of these line segments are parallel (but not equal in length) and two are nonparallel.(in the UK, this is called a trapezium)British DefinitionA trapezoid is a closed plane figure consisting of four line segments/sides; NONE of these line segments are parallel to any of the other line segments of the quadrilateral.(in the US this is just a quadrilateral)*(see the related links for images of trapezoids)

Technically, lines are continuous, so parallelograms are actually composed of line segments. The line segments composing the sides of the parallelogram, come in two pairs in 2D space. Each pair is composed of two line segments that are parallel to each other, but do not occupy the same line. The two pares of line segments must all meet to then form a quadrilateral.

Quadrilateral is a mathematical term used for any figure with its area bounded by four straight line segments forming a closed path.
