A regular heptagon (or septagon, if you prefer) has seven equal sides and seven equal angles, and none of the sides is parallel to any other one. There is a bit more.
There are an infinite number of other (irregular or non-regular) heptagons that may have at least one pair of parallel sides, and an infinite number that do not have any sides that are parallel.
There is no such shape. There is a heptagon (7-sides) or an octagon (8 sides) but not hectogen!
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.
a heptigon
For a shape to have parallel sides it needs at least 4 sides
There is no such shape. There is a heptagon (7-sides) or an octagon (8 sides) but not hectogen!
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.
