All concave polygons are irregular because the interior angles are of different measures.Ī convex and concave polygon can be easily distinguished based on their properties.If a line segment is drawn across a concave polygon, it touches more than 2 sides.There is at least one vertex in a concave polygon that seems to be pushed inwards to give that distinct 'cave' shape to the polygon.Some of the diagonals in a concave polygon may lie partly or fully outside it.A concave polygon has at least one angle which is a reflex angle, that is, it is more than 180° and less than 360°. Observe the following figure which shows concave polygons.Ī concave polygon has some distinct properties that help to distinguish it from other polygons. If any of the diagonals of a polygon are formed partly or fully outside the polygon, then it is called a concave polygon. Concave Polygon DefinitionĪ concave polygon is defined as a polygon in which one or more interior angles are more than 180°. For example, a star is a concave polygon. A concave polygon looks like a polygon in which at least two sides seem to be pushed inwards. If any interior angle in a polygon measures more than 180°, then that is a concave polygon. A polygon that is not convex is a concave polygon.
