Not all polygon have two pairs of parallel sides. For example, a square will, but not a triangle.
A polygon need not have ANY perpendicular or parallel lines. For example, consider an equilateral triangle. It can happen that two sides of a polygon, extended if necessary, meet at a point where they form a 90 degree angle. Those two lines are perpendicular. There may be pairs of lines such that, no matter how far you extend them in either direction, they will never meet. Such lines are parallel. A triangle cannot have parallel lines but it can have perpendicular lines. Any polygon of 4 or more sides can have sides that are perpendicular or parallel (or some of each).
It has two pairs of parallel lines so yeah
A square has 2 pairs of opposite parallel lines.
16. 8 through pairs of opposite vertices and another 8 through the midpoints of opposite sides.
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 has.
A square A parallelogram
What polygon had 6 sides and 6 angles
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.
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.
