Hint: Polygons are defined as the two-dimensional shapes. Polygon is derived from the Greek word, poly means “many” and gon means an “angle. There are two types of polygons. They are Regular and irregular polygons. Polygons are named on the basis of the sides they have.
Complete step-by-step answer:
If any polygon has all equal angles and all equal sides are known as the regular polygon. If all the angles and the sides are not equal then it is known as irregular polygon.
As shown in the above figure we can see the nine-sided closed figure. It has nine equal sides and so nine equal angles too. Figure above ABCDEFGHI is the polygon with nine sides and so known as nonagon. Here we can observe that each side of the nonagon exactly intersects the other sides of the figure.
So, yes, we do have a nine-sided shape in the geometry.
In geometry, the nine-sided shape is known as the nonagon or enneagon. In Nonagon, the number of vertices and the edges is nine. Also, each internal angle is equal to $ 140^\circ $ since equal sides of the closed figure gives equal angles.
Note: Two dimensional shapes are also known as the polygons. They can be convex, concave or the star. It can have as many straight lines and the shapes are closed since the lines are connected up. In polygons each side intersects exactly two other sides but only at their endpoints and the points are non-collinear having only one common endpoint.
