Question

# Is the figure a polygon? Is it convex or concave?

- Not a polygon, convex
- Polygon, convex
- Not a polygon
- Polygon, concave

Hint:

### General synopsis of Polygon.

## The correct answers are: Polygon, convex, Not a polygon

### * 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

* Convex polygon :

This is a type of polygon with all the interior angles strictly less than 180 degrees. The vertex of a convex polygon always points outwards from the center of the shape.

>>>Given That:

>>>There are two 90 degree angle. Hence, the total sum of angles obviously greater than 180 degrees.

>>>Hence, the given figure is Convex Polygon.

>>>The Convex polygon is called as the polygon that has sum of interior angles greater than 180 degrees.

>>>Therefore, the given figure is a convex 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.
