concave
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.
Is a concave polygon.
is this a polygon? is it concaver or convex
A simple polygon that is not convex is called concave, non-convex or reentrant. A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
No. There can be no regular concave polygon.
A concave polygon has lines that curve inwards whereas a convex polygon has lines that curve outwards and they are found on and inside spheres
These terms describe polygons. To identify a polygon as convex, we draw a segment from any vertex to any other vertex. This segment cannot go outside of the polygon. Non-convex is concave. If we draw a segment from a vertex to any other vertex, at least one of the segments will go outside of the 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 concave polygon has at least one interior angle greater than 180 degrees. A convex polygon has none of those.
