A concave hexagon or a concave octagon.
A concave irregular hexagon can have up to 6 right angles. A convex irregular hexagon can have up to 3 right angles.
A concave hexagon is one in which one or two interior angles are greater than 180 degrees. With one reflex angle, it would look like a chevron.The browser used here is pretty grim for graphics but, the following is a crude rendition. Ignore the dots - they are required to get the spacing approximately right!_____\.......\..\.......\../......//____/
None. Though there can be ten if the hexagons are concave hexagons.
It looks like four equilateral triangles that have been put together so that one vertex of each meet at a point.
If it's a regular hexagon, it can't be concave. If it's an irregular hexagon,then it can be concave if it wants to, but it doesn't have to be.
It is a hexagon with a reflex angle.

It is concave because it is going in so it is going in the cave
Out of a hexagon, only a hexagon.If you have many hexagons, they can tessellate a plane, although the boundaries of this shape will be concave in parts.Out of a hexagon, only a hexagon.If you have many hexagons, they can tessellate a plane, although the boundaries of this shape will be concave in parts.Out of a hexagon, only a hexagon.If you have many hexagons, they can tessellate a plane, although the boundaries of this shape will be concave in parts.Out of a hexagon, only a hexagon.If you have many hexagons, they can tessellate a plane, although the boundaries of this shape will be concave in parts.
concave, equilateral
You start creating a concave hexagon from four triangles by placing the smallest triangle in the middle to serve as a base for the other three. Line up the bases on each triangle with the sides of the smallest one to end up with six sides forming a concave hexagon.

A regular hexagon and 3 classes of convex hexagons, plus concave hexagons will tessellate.
The definition of concave is a curved like a segment of the interior of a circle or hollow sphere.
