A regular triangle, quadrilateral (i.e., square) and hexagon may be used.
A regular polygon requires all sides to be the same length; in a rectangle not all four sides are the same length (they form two pairs of sides of equal length) and so it is not a regular polygon.
A regular polygon is a special kind of convex polygon - one in which all the sides are of the same length and all the angles are equal. Convex and concave polygons form disjoint sets: so no concave polygon can be regular.

It is impossible to have a two-sided regular polygon with equal length sides. The two sides would merely form an open angle, with no closed third side.
