Calculate the various properties of Area of Polygon for given values.
|Regular polygons||The polygon having all sides and interior angles of the same size.|
|Irregular polygons||Every side and angle may be of different size.|
|Convex polygons||Every interior angles are < 180° and every vertices "point outwards" away from the interior. The regular polygons are always convex.|
|Concave polygons||One or more interior angles > 180° and some vertices push "inwards" towards the interior of the polygon.|
|Crossed polygons||The The polygon where any or more sides are crossing back over another side means forming multiple smaller polygons.|
