a quadrilateral
A regular polygon is a polygon whose sides are equal length and whose angles are all the same value. A non regular polygon is just the opposite of a regular polygon.
Any polygon whose sides are equal in length, such as a square, is a regular polygon.
Triangles, rectangles and octagons are all examples of a polygon. A polygon is a polygon whose sides are the same length and whose interior angles are the same measure

A non regular or irregular polygon is a polygon whose sides are not all the same length

A parallelogram.
A regular polygon is a polygon whose sides are all the same length, and whose angles are all the same. The sum of the angles of a polygon with n sides, where n is 3 or more, is 180° × (n - 2) degrees.So the amount of sides can vary. 6/8/exc...
regular polygon-all the sides are the same length and the angles have the same measurement. polygon-a closed plane figure whose sides are segments that intersect at their endpoints.

There is no way to know.If two opposite sides are parallel and of equal length, then the quadrilateral is a parallelogram (rectangle, rhomboid, square, or rhombus).
