WebArea is defined as the total space taken up by a flat (2-D) surface or shape of an object. The space enclosed by the boundary of a plane figure is called its area. The area of a figure is the number of unit squares that cover the … WebThe radius of the circumcircle is also the radius of the polygon. The "inside" circle is called an incircle and it just touches each side of the polygon at its midpoint. The radius of the incircle is the apothem of the polygon. (Not all polygons have those properties, but triangles and regular polygons do). Breaking into Triangles
