parallelogram
A rectangle perhaps?
Any polygon with more than 3 sides can have two pairs of parallel sides.If it has only four sides and they make two parallel pairs, then it's a parallelogram.
A square A parallelogram
A square
It has two 5-tuples and 5 pairs of parallel lines. It need not have any line of symmetry.
A rectangle perhaps?
A nonagon is a nine-sided polygon. In a nonagon, there are four pairs of parallel lines. This is because the nonagon can be divided into three sets of parallel lines, each containing three parallel lines. Each set of parallel lines consists of three pairs of parallel lines.
rhomboid
Any polygon with more than 3 sides can have two pairs of parallel sides.If it has only four sides and they make two parallel pairs, then it's a parallelogram.
A square has.
A square A parallelogram
What polygon had 6 sides and 6 angles
A square
It has two 5-tuples and 5 pairs of parallel lines. It need not have any line of symmetry.
A irregular polygon will not have any parallel lines. :)* * * * *Not true. A rhombus is an irregular polygon and it has two pairs of parallel line!An irregular pentagon can have parallel lines.However, a triangle or a conic section cannot.
Square
A decagon has 10 sides. Any regular polygon with four or more sides will have pairs of sides that are parallel. A decagon will have 5 pairs of parallel sides.
