Convex . . . "curved out", like the outside of a balloon, the outside of a smooth hubcap,
and the top of a half-eaten ice-cream cone.
Concave . . . "curved in", like the top of the ice-cream in the tub after the first five cones
have been scooped out, the mark a rock makes in snow, and the inside of a soup bowl.

What makes a polygon a concave?
Not all polygons are concaves. For it to be a concave, it must have an outline or surface pointing inwards, like a depression. The opposite is "convex." Most regular polygons are convex, while some will be concave. Think about it this way: con = with (generally, and sometimes), cave = going inward, or bending inward, etc. CONCAVE is the result of those two put together, so it must mean that one or more of its outlines or surfaces must be pointing inwards! :)
How do you work out size of hexagon?
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.
