A quadrilateral with two parallel sides is a trapezoid.
A square and a rhombus
A parallelogram is flat, with four straight sides, with opposite sides being parallel.
If the shape (a quadrilateral) has only 2 parallel sides, it is a trapezoid (UK trapezium).A shape with four sides and two sets of parallel sides is a parallelogram (rectangle, square, rhomboid, rhombus) because these figures have four sides and two sets of parallel sides.
A square (i am pretty sure) has 2 sets of parallel sides and four parallel sides.
Atrapezoidhas four sides and only two of the four sides are parallel. A square,parallelogram, and kite have four sides and have multiple pairs of parallel sides.
The name of the four-sided shape that has only one pair of parallel sides is known as a trapezoid. The other two sides are not parallel to each other. There are many other shapes with more than four sides that have one pair of parallel sides but these typically don't have special names. So assuming the question is only referring to four-sided figures, the answer is a trapezoid.
It has two pairs of parallel sides.
A regular octagon has four pairs of parallel sides.
A rectangle is a shape that has four sides with two parallel lines.
Any polygon with four or more sides can have parallel sides.
A parallelogram is an quadrilateral (a figure with four edges and four vertices) with two sets of parallel sides. A trapezoid, also known as a trapezium, is a shape with four sides with a pair of parallel sides.
A quadrilateral has four sides and four vertices but no sides need to be parallel although they can be.
