No. There can be no regular concave polygon.

no because it is curved I think and polygons cannot be curved.

no

no

No.

No.

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

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.

FALSE my friends

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.

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

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.

false

true

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.

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).

no it cannot , because a regular polygon is a shape with equal sides, and for it to be concave or convex some sides have to jut out or in See related link below for more information

No! Regular polygons must have equal side lengths and equal angles.

It depends if the polygon is convex or concave but if it is a regular polygon it would have 560

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.

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.
