A rectangle is a shape that has four sides with two parallel lines.
None. A parallel is not a shape and so does not have any sides.
Any polygon with four or more sides can have a pair of parallel sides. It is also possible to to have non-polygonal shapes - eg a cigar-shape - that has parallel sides.
Any shape wit four of more sides can have one pair of parallel sides.
square
For a shape to have parallel sides it needs at least 4 sides
A 25-sided shape would have no parallel sides !
A rectangle is a shape that has four sides with two parallel lines.
If it has four equal sides, then two parallel sides implies two PAIRS of parallel sides. The shape is a rhombus.
Any polygon with four or more sides can have parallel sides.
A geometric shape with only one set of parallel sides is a trapezoid.
None. A parallel is not a shape and so does not have any sides.
shape no pairs of perpendicular sides
A trapezoid is a shape that has 4 sides and 2 parallel sides. The sides that are parallel are called the bases.
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.
Any polygon with four or more sides can have a pair of parallel sides. It is also possible to to have non-polygonal shapes - eg a cigar-shape - that has parallel sides.
A shape with parallel sides but no right angles is called a parallelogram
