The total of the interior angles of a polygon is given by:
total_of_interior_angles = 180° × (number_of_sides -2)
A regular polygon has every interior angle the same, and the size of each angle is given by:
size_of_interior_angle = total_of_interior_angles / number_of_sides
→ size_of_interior_angle = 180° × (number_of_sides -2) / number_of_sides
But as number_of_sides - 2 is (always) less than number_of_sides, (number_of_sides -2) / number_of_sides is less than 1 and so the size_of_interior_angle is less than 180°.
To be a concave polygon, at least one interior angle must be greater than 180°.
But as a regular polygon has all interior angles less than 180°, no regular polygon can be concave.

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 qudrilateral be a regular polygon?
no
Is a concave shape a regular polygon?
no

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 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
Is a concave polygon is regular?
By definition a regular polygon cannot be concave. Concave polygons contain one or more interior angles that are greater than 180 degrees, and regular polygons can never have an interior degree greater than 180 degrees.
