- 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.

Concave Polygon Definition. A polygon has at least one angle that measures more than 180 degrees, which is called a concave polygon. The vertices (endpoints) of this polygon are inwards as well as outwards. They are just the opposite of the convex polygons.
- 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.

- 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.
A concave polygon is a polygon in which at least one interior angle is a reflex angle (angle greater than 180° but less than 360°). A concave polygon has at least 4 sides. It means that a triangle is always a convex 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...

- 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.
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]
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.
Aug 3, 2023 · What is a Concave Polygon. A concave polygon, also known as a non-convex polygon, has at least one of its interior angles measuring more than 180°. Some diagonals of a concave polygon lie outside the closed figure. All concave polygons are irregular since all the interior angles are of different measures.
A convex polygon has no angles pointing inwards. More precisely, no internal angle can be more than 180°. If any internal angle is greater than 180° then the polygon is concave. ( Think: concave has a "cave" in it) A simple polygon has only one boundary, and it doesn't cross over itself.
