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.

You have to see it both the polygons measures to the same degree's & the same shape then that make's it congruent.
