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.
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
No. There can be no regular concave polygon.
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.
A concave polygon is a type of polygon that has at least one interior angle greater than 180 degrees, which causes it to "cave in" toward the interior. This results in at least one vertex pointing inward, creating a shape that can have both convex and concave angles. Additionally, a line segment drawn between two points within a concave polygon may lie outside the polygon, distinguishing it from convex polygons where all such segments remain inside. Concave polygons can have any number of sides, but their defining characteristic is the presence of at least one concave angle.
convex
A polygon can be convex, which means Convex Polygon: A polygon that has all interior angles less than 180° Concave Polygon A polygon that has one or more interior angles greater than 180° A Complex polygon is neither convex or concave. A star polygon is an example of a complex polygon. If you look in google images, there are tons of pics of them.
