A concave polygon is defined as a polygon in which one or more interior angles are more than 180°. If any of the diagonals of a polygon are formed partly or fully outside the polygon, then it is called a concave polygon. Observe the following figure which shows concave polygons.
A Concave polygon is a polygon that has at least one interior angle greater than 180 degrees. It must have at least four sides. The shape of the concave polygon is usually irregular. A concave polygon is a polygon which is not convex. This polygon is just the opposite of a convex polygon.
- A concave polygon is a polygon that has at least one of its interior angles greater than 180 degrees.
- A concave polygon has at least four sides.
- A convex polygon has all its interior angles less than 180 degrees whereas a concave polygon has at least one interior angle more than 180 degrees.
- Divide the concave polygon into separate triangles, by drawing diagonal lines from one vertex point to other vertices. Now find the area of all the...

- Rhombus is a type of parallelogram having all sides equal in length and opposite angles equal in measure. All the parallelograms are convex polygons.
- An arrow is a two-dimensional shape that has a straight line with one end-point. Since it is not a closed shape thus it cannot be a polygon.
Concave polygon. An example of a concave polygon. A simple polygon that is not convex is called concave, [1] non-convex [2] or reentrant. [3] A concave polygon will always have at least one reflex interior angle —that is, an angle with a measure that is between 180 degrees and 360 degrees exclusive. [4]
Concave polygons are irregular in shape. A concave polygon can be divided into triangles or other smaller polygons. Then, the area of these shapes can be calculated with the appropriate formulas and these areas can be added together to get the area of the concave polygon.
- The perimeter of a concave polygon is calculated in the same way as the perimeter of convex polygons. All the sides of the polygon are added to fin...
- An arrow is a concave polygon because it fulfills all the conditions of a concave polygon. It has interior angles that measure more than 180° and o...
- A regular polygon is a polygon that is equilateral and equiangular whereas a concave polygon is a polygon in which at least one angle is more than...
- No, a triangle is not a concave polygon as there are no diagonals in a triangle. Also, the sum of angles of a triangle is 180°.
- A star is a concave polygon.
A concave polygon is defined as a polygon with one or more interior angles greater than 180°. It looks sort of like a vertex has been 'pushed in' towards the inside of the polygon. Note that a triangle (3-gon) can never be concave. A concave polygon is the opposite of a convex polygon. See Convex Polygon .
May 24, 2024 · A concave polygon is a polygon that is not convex. A simple polygon is concave iff at least one of its internal angles is greater than 180 degrees. An example of a non-simple (self-intersecting) polygon is a star polygon. A concave polygon must have at least four sides.
