A nonconvex polygon is a concave polygon. All polygons with 4 or more sides can be concave. An arrowhead is an example of a concave quadrilateral. The back of an envelop (where the sides are folded and glued together) is a concave pentagon.
a concave polygon is that polygon whose at leat one of the angles is greater than 180 degree
No.
A concave hexagon or a concave octagon.
i dont think any1 knows * * * * * A concave polygon has at least one reflex angle. Equivalently, in a convex polygon, a line joining ANY two points in (or on) the polygon lie wholly within (or on) the polygon. In a concave polygon there are at least two points for which the line joining them does not lie wholly inside (or on) the polygon.
