Easy answer: a star icon or the apple logo are examples of what a concave polygon looks like.A concave polygon has 1 interior angle greater than 180 degrees.you can see an example on:http://en.wikipedia.org/wiki/Convex_and_concave_polygonshttp://www.mathopenref.com/polygonconcave.html
It would look a bit weird, but the only way to achieve this is by curving the sides or by making a concave hexagon.
Well, isn't that a happy little question! A jeweller's mirror is usually concave, which means it curves inward like a bowl. This helps magnify the reflection and make it easier to see small details while creating beautiful pieces of art. Just remember, whether concave or convex, mirrors always reflect the beauty that's within you.
Concave is a property of [irregular] polygons. A parallelogram cannot be concave.

First you have to understand concave. Concave is a term of the curve of the deck. Not from nose to tail, but from side to side. You will notice the board dips down in the middle (or comes up on the sides, however you want to look at it). This allows your heels/toes to flick the board for kickflips and heelflips. The deeper the groove (or the more the side come up) the more the concave. So, for a board to have mellow concave it is more flat.
yes
doctors use concave mirror for examination of ear nose throat and eyes because when something is placed between focal length and pole of a concave mirror the doctor sees an enlarged, erect and virtual image of his nose, ears etc..
