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

This figure is not polygon and it is a concave

Step-by-step explanation:

A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons - a polygon, by definition, is made up of straight lines.

And a convex is like a circle. But a concave having an outline or surface that curves inward like the interior of a circle or sphere.
