No. There can be no regular concave polygon.
A concave quadrilateral. An arrowhead or a delta, for example.
Concave, because you can connect the corners from the outside.
If you can differentiate the function, then you can tell that the graph is concave down if the second derivative is negative over the range examined. As an example: for f(x) = -x2, f'(x) = -2x and f"(x) = -2 < 0, so the function will be everywhere concave down.
Yes. All polygons with 4 or more sides can be concave. An arrowhead is an example of a concave quadrilateral. The back of an envelop (where the sides are folded and glued together) is a concave pentagon.
If an object is concave, it means that is contains a surface that curves inward. Eyeglass lenses and bowls, for example, can both be said to be concave.

A nonconvex polygon is a concave polygon. All polygons with 4 or more sides can be concave. An arrowhead is an example of a concave quadrilateral. The back of an envelop (where the sides are folded and glued together) is a concave pentagon.

No. There can be no regular concave polygon.
Lots of different things curve in. Something that curves inwards can also be called concave, a spoon is an example of something that is concave. A bowl is also concave and curves inward.
Concave means that there is a dip in the object, like it has caved in. Bi-concave means that it is dipped in on two sides of the object. A good example is a red blood cell. It is a bi-concave disk - it has dips on two sides of it.
