A regular polygon has all its sides equal and all its angles equal. One consequence is that no angle can be reflex (between 180 and 360 degrees). A concave polygon, on the other hand, must have at least one angle that is a reflex angle.
The line joining any two points inside any convex polygon (and that includes regular ones) must lie wholly within the polygon. In a concave polygon, it must be possible to find two point inside the polygon such that the line joining them crosses the boundaries of the polygon.

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.
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.
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.
Can a concave qudrilateral be a regular polygon?
no

No, a concave polygon cannot be a regular polygon.
Diffrance between regular polygon and a concave polygon?
A regular polygon has all the side the same length and the same measures of angels. * * * * * Or measures of angles, even! A concave polygon has at least one angle that is reflex (between 180 and 360 degrees).
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.
How do you draw a regular concave polygon?
it is impossible
What is the difference between a regular polygon and non regular polygon?
Regular polygon is equilateral and equiangular. Irregular polygon is non-equilateral and non-equiangular.
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.
