it's a trapezoid
It looks like its the heading on an exercise and it means for the given polygons name them. The polygons will either be pictures or descriptions (like "it has four equal sides and two pairs of parallel sides").
There is no mathematical limit to the number of sides that a polygon can have. As the number of sides increases the polygon will become more and more like a closed curve - a regular polygon will become like a circle. The size of the polygon and accuracy of measurement will determine when it is no longer possible to distinguish between the polygon and the curve. Nevertheless, the two shapes will be mathematically different objects.
If the polygon is also a quadrilateral (4 sided polygon) then the answer is trapezoid. But there are many multi-sided polygons that could have a pair of opposite parallel sides - hexagon for example or consider the following pentagon: /\ | | -- That was difficult, but you get the idea. It looks like a house.
|\/**\/| |/\__/\| an irregular shape like the one poorly represented above. the top horizontal sides are parallel and the side vertical sides are also parallel, but there can be other non parallel sides like the \/'s an /\'s. depending on the situation this question is being asked for this answer might be adequate. hope this helped. p.s. the in the middle of the shape can be ignored because they are there only to hold shape (spaces didn't work) and the asterisks at the top should be a line (same reasoning) Any regular even-number sided polygon will have at least two pairs of parallel sides. A regular hexagon will have 3 pairs of parallel sides.

Well a nonagon is a nine sided polygon. If you make the lines or sides parallel, then you will have a parallel figure. Or some parallel lines on a figure (polygon). If you choose to make your polygon (nonagon) have a pair of congruent sides, then your polygon will have some congruent sides. Therefore it really matters what your shape looks like. For example, a quadrilateral can be a square or a kite (or many others but I'm just using these) a kite might have no parallel lines and a square may have 2 sets of parallel lines. Do you get it? Does that answer your question? FYI: A nonagon is also known as a enneagon :)
A polygon is a closed two-dimensional figure, and a trapezoid is also. Therefore, a trapezoid is a polygon. *A trapezoid is a four-side polygon with only two parallel sides, which looks like a distorted square.
a house. It has 5 sides like a polygon
It looks like its the heading on an exercise and it means for the given polygons name them. The polygons will either be pictures or descriptions (like "it has four equal sides and two pairs of parallel sides").
Just like a triangle is a polygon with 3 sides, A Quadrilateral(quad) is a polygon with 4 sides. Pentagon is a polygon with 5 sides and hexagon is one with 6 sides.
A polygon with only 1 pair of perpendicular sides is called a trapezoid. In a trapezoid, one pair of opposite sides are parallel, while the other pair are not parallel and intersect at a right angle. The sum of the interior angles of a trapezoid is always 360 degrees. Examples of trapezoids include isosceles trapezoids, right trapezoids, and scalene trapezoids.
A parallelogram is a four sided planar (two-dimensional) polygon that has two pairs of parallel sides. Google parallelogram for an image.
A Heptagon may have 0, 2, 3, 4, 5, 6, or 7 parallel sides.
The quadrilateral you are describing is a trapezoid. A trapezoid is a four-sided polygon with at least one pair of parallel sides. In the case you mentioned, where both pairs of opposite sides are parallel but of different lengths, it is known as a trapezoid. The parallel sides are referred to as bases, and the non-parallel sides are the legs of the trapezoid.
A polygon is a shape that is closed with straight sides and the sides do not overlap like these. I don't know if an arrow is a polygon.
There is no mathematical limit to the number of sides that a polygon can have. As the number of sides increases the polygon will become more and more like a closed curve - a regular polygon will become like a circle. The size of the polygon and accuracy of measurement will determine when it is no longer possible to distinguish between the polygon and the curve.
