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.

A concave hexagon or a concave octagon.
A concave hexagon is a hexagon that has one or two reflex angles. With one reflex angle, it will resemble a chevron - like a stripe on a police or army uniform, or the letter V which has thickness. With two reflex angles, it will resemble an hourglass with straight sides.
A concave irregular hexagon can have up to 6 right angles. A convex irregular hexagon can have up to 3 right angles.
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.
