Every internal angle is less than 180 degrees.A polygon that is not a convex polygon is referred to as a concave polygon.It can be cut into a set of convex planes.At least one interior angle is greater than 180 degrees.Convex polygons are easier to draw in comparison to concave polygons.Д¬omparison between Convex and Concave Polygons:ДЄ polygon with one or more interior angles greater than 180 degrees is referred to as a concave polygon.ДЄ polygon of which all interior angles are less than 180 degrees is known as a convex polygon. All regular polygons are convex (a polygon that has all sides equal and all interior angles equal). However, in a concave polygon, some diagonals will always lie outside the polygon. It is important to note that all the diagonals of a convex polygon lie entirely inside the polygon. In 3 dimensional shapes, the same test can be performed to differentiate between the two. On the other hand, if the same process is repeated in a concave shape, then the line is able to pass through more than two of the lines. If a line is drawn that passes through the polygon, and it always passes through only two of the lines or polygons making up the shape, then in that case, the shape of the polygon is convex. A simple line test can be used to distinguish a concave polygon with a convex polygon. In other words, a concave polygon exists with an interior reflex angle. In other words, it has no internal angle that is greater than 180 degrees.ДЄ polygon with any of the internal angles greater than 180 degrees is known as a concave polygon. A convex polygon is the one in which none of the angles point inwards. One such type is based on the internal angles. On the other hand, a polygon with one or more interior angles greater than 180 degrees is referred to as a concave polygon.ДЄ polygon can be defined as a closed plane figure (a two dimensional shape) that consists of three or more line segments. Key Difference: A polygon whose all interior angles are less than 180 degrees is known as a convex polygon.
