Any conic section.
A pentagram.
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.
A circle does not have any pairs of parallel sides. In geometry, parallel sides are defined as sides that are always the same distance apart and will never intersect. Since a circle is a curved shape with no straight sides, it does not have any pairs of parallel sides.
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.
None. A parallel is not a shape and so does not have any sides.
A geometric shape with only one set of parallel sides is a trapezoid.
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.
