Yes. A rectangular screen. a rectangular door and windows, a lampshade made of pentagons (forming a dodecahedron).

If you mean a 4-sided polygon, then that is a quadrilateral. See related link for more information on polygons.
Potential answers: shapes, polygons, quadrilaterals [four-sided polygons], parallelograms [quadrilaterals with opposite sides of the same length and parallel to each other].
See the link for a worksheet.
All sorts of polygons can create tessellations. See attached link for some examples: http://http://en.wikipedia.org/wiki/Tessellation

See the Related Link below for pictures of polygons.
Some examples of polygons include circles, triangles, squares, rectangles, pentagons, and hexagons. These are examples of 'simple polygons,' in that none of the lines overlap and intersect each other, such as in a pentagram, which is a 'star polygon.'

They would be equilateral concave polygons. See the related link to see some diagrams.
A polygon is a two-dimensional shape enclosed by lines only, not curves. So triangles, squares, rectangles, and octagons are examples of polygons. Circles, ellipses, and annuli are some shapes that are not polygons.

Non-polygons include shapes that do not have straight edges or a closed structure. Examples are circles, ellipses, and parabolas, which consist of curved lines. Additionally, shapes like stars or figures with intersecting lines that do not form a closed shape, such as a spiral, also fall into the category of non-polygons.
