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.

Hexagon
A hexagon is a planar shape, meaning that it is by definition two dimensional. Therefore, there cannot be a 3D hexagon.
Every hexagon has six sides. That is the definition of "hexagon".If it did not have six sides, then it would not be a 'hexagon', andwe would not be having this discussion.
a prism with a hexagon for a base.
A hexagon is any polygon (closed figure with straight sides) with six (6) sides and angles.
A convex hexagon is a six-sided polygon in which all interior angles are less than 180 degrees.
A parallelogram is by definition made of two pairs of parallel lines; it is always a four sided figure. A hexagon is a six sided figure, so it cannot be a parallelogram.

a hexagon looks like a stop sign but with only six sides. By definition a hexagon is a polygon with 6 straight edge sides and no crossing lines. A regular hexagon is one where all 6 sides are the same length. Chicken wire and honeycombs commonly come in the form of multiple regular hexagon shapes. The heads on bolts are commonly hexagons. Hex wrenches are made to fit in hexagonal openings and have a hexagon cross-section.
a polygon with 6 sides * * * * * The fact that is has six sides makes it a hexagon but that does not explain ""convex". A convex polygon is one in which none of the angles is a reflex angle. An alternative definition of convex is that a line joining any two points inside the hexagon is wholly inside the shape.
"Having the same center" is the meaning of concentric. A regular hexagon in a concentric circle can be viewed by using the link and looking at the "active construction" window where there is a short animation of the construction of a hexagon inside a circle. It is posted by our friends at Wikipedia, where knowledge is free.
No pentagon has six sides. By definition a pentagon has five sides only; having six makes it a hexagon.
When referring to it as a hexagon is not a faux pas.
