Trapezoid. It has two parallel lines on opposite sides.
You can construct any polygon with more than 4 sides such that two sides are parallel. A quadrilateral in which two lines are parallel is called a trapezoid.
Answera polygon that has two right angles and one set of parallel lines is a hexagon
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).
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 square
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.
It can be any polygon with more than three sides.
No not always as for example a 3 sided triangle has no parallel sides
A square A parallelogram
No it can't, because if a triangle has two parallel lines then it ceases to be a triangle and becomes quadrilateral or a polygon.
Parallel lines are at least two lines that never cross and run forever.
