Most of the time.If a quadrilateral contains no parallel lines or two pairs of parallel lines then it is not a trapezium.
Not if the two pairs give rise to 4 parallel lines.
A quadrilateral with 2 pairs of parallel line segments is a parallelogram. Parallelograms include rectangles, rhombuses, and squares.
A quadrilateral doesn't have to have any pairs of parallel lines. It depends what kind of quadrilateral you are talking about... Rectangle- Yes (2 pairs) Square- Yes (2 pairs) Trapezoid- Yes (1 pair) Parallelogram- Yes (2 pairs) Rhombus- Yes (2 pairs)
A quadrilateral has 4 sides, 2 in which never intersect. Therefore, the lines that don't intersect are called parallel. There are 4 parallel sides but has 2 pairs of parallel sides.
