A concave Hexagon is that hexagon which has one of its internal angle greater than 180 degrees. It can have 8 diagonals. As compared to regular hexagon (Also convex hexagon) it has one less number of diagonals. This is because one line joining two of its vertices (that are at the end of sides forming >180 angle) fall outside the hexagon.

A hand file where both surfaces are flat. Used to file down metal where the surface requires a flat finish. Other files in the work shop are curved concave, curved convex ,triangular and square. Each used to specific shape filing.

Pretty simple really: Vertices are corners and edges are boundaries so, a hexagon has six of each.
It is concave because it is going in so it is going in the cave
A regular hexagon and 3 classes of convex hexagons, plus concave hexagons will tessellate.
It depends on what the angles are. If any of the angles have measurements greater than 180 degrees, it is concave. If all angles are less than 180 degrees, then it is concave. For example, a regular hexagon has six 120 degree angles, so it is convex. If there was a hexagon with five 90 degree angles and one 270 degree angle, it would be concave.
A concave irregular hexagon can have up to 6 right angles. A convex irregular hexagon can have up to 3 right angles.
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
It can be convex or concave.
convex and concave
The answer depends on what you mean by size: its area (more likely) or perimeter. In either case, the answer depends on what information you have about the hexagon: whether it is regular, irregular but convex, or concave.
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.
A hexagon could be any of those, and more than one at the same time. If it's regular, then it's all the others except 'concave'. On the other hand, if it's concave, then it's not any of the others.
