Question
Identify the correct statement for the following figure.
- Convex
- Concave
- Equilateral
- Regular
Hint:
General Synopsis of Concave polygon.
The correct answer is: Concave
*In mathematics, a polygon is a closed two-dimensional figure made up of line segments.
* Poly means many gon means angle. Hence, polygon is a closed figure that is made of many angles.
*In General there are 4 types of polygons. They are:
Regular Polygon
Irregular Polygon
Convex Polygon
Concave polygon
Given That:
>>> The interior angle of the given figure is greater than 180 degrees.
>>>Concave Polygon:
If one or more interior angles of a polygon are more than 180 degrees, it is known as a concave polygon. A concave polygon can have at least four sides—the vertex points towards the inside of the polygon.
>>>Hence, It is considered as a Concave polygon that is equiangular.
Concave is when a side can be turned into a line that goes on the inside of a shape.
>>>Hence, the given figure comes under concave polygon.

What is the general form of naming a polygon?
One can find this with a small trick. The student should learn to break the word. For example, Hexagon: Hexa+Gon. Now, as we know that hexa is six. Similarly, if a polygon has ‘n’ sides, then the polygon would be named as n-gon.
