Question

Answer 1

regular

irregular

Answer 2

Many ways.  There are regular polygons, which have all equal length (congruent) sides, and irregular, which have different length sides and don't have regular shape.  An example of a regular polygon is a stop sign.  It is a regular octogon.  An eight sided shape with different lengths and no symmetry would be irregular.

Also, they can be classified as parallelograms, trapezoids, rhombuses, rectangles and squares.  All squares are rectangles, all rectangles are parallelograms.  All  rhombuses are parallelograms.  All these shapes are polygons.
