No. It is impossible.
The definition of a regular polygon is a polygon with equal angles, and equal sides.
For a polygon to be concave, it has to have at least one angle more than 180 degrees, and a a polygon cannot consistently have angles more than 180 degrees.

Is a star shape an irregular polygon?
Not all are. Not only is it a concave shape, but the interior angles can vary. For a polygon to be regular, it must be equilateral and equiangular.
A polygon that is not convex?
Is a concave polygon.
Is it possible to create a regular tessellation with a regular polygon?
Inly if the polygon has 3, 4 or 6 sides.
What is a concave angle?
A concave angle is an angle, of a polygon that caves in.
Name each polygon tell if it appears to be a regular polygon?
It is not possible to name each polygon since there are infinitely many of them. There is no relationship between whether a polygon is regular and the number of sides or angles that it has. So, there is no way to determine, from its name, if a polygon is regular.
A square is an example of a quadrilateral that is both a regular concave polygon and a regular convex polygon?
No. There can be no regular concave polygon.
Is a concave polygon a regular polygon?
No, a concave polygon cannot be a regular polygon.
What are the similarities between regular polygon and a concave 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.
Can a concave quadrilateral be a regular polygon?
No.
Can a concave qudrilateral be a regular polygon?
no
Is a concave shape a regular polygon?
no
Can a concave figure be a regular polygon?
No.
Can a concave polygon be a regular polygon?
No.No! It is not possible.Regular polygon:Polygon in which all the sides are equal and all the interior angles are equal is called as a regular polygon.Concave polygon:A polygon that has one or more interior angles greater that 180o is called as a concave polygon.It is not possible to have polygon with all sides equal and greater than 180o.Source: www.icoachmath.com it is possibleA concave polygon had to be irregular.
How do you draw a regular concave polygon?
it is impossible
What is the difference between a concave polygon and a convex polygon?
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
For a given number of side there exist both a regular concave polygon and a regular convex polygon?
A concave polygon cannot be regular because regularity requires all angles (and sides)to be of equal measure. Even if you drop the requirement of regularity, there cannot be a concave triangle.
Why is a star polygon concave?
because the point of origin would be on an outer point and around it the walls seem to cave in making it seem concave, in comparison to a regular polygon. When checking for concave polygons always compare what you are looking at to a regular polygon
