The parallel sides of a polygon are sides that are segments of parallel lines. A polygon need not have any parallel lines. A triangle, for example, is a polygon that cannot have parallel lines.
no its not a polygon
Triangles never have parallel lines
There can be no convex polygon with three parallel sides. There are concave polygons with 6 or more sides that have three parallel lines.
Trapezoid. It has two parallel lines on opposite sides.
parallel lines.
Answera polygon that has two right angles and one set of parallel lines is a hexagon
Any polygon with four or more sides can have perpendicular and parallel lines.
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).
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.
parallelogram
polygon or as we call it a trapezium
