The area of a polygon is the total space covered by a polygon. However, we can calculate the sum of all interior or exterior angles of any convex polygon.
The sum of all interior angles of this polygon is equal to 900 degrees, whereas the measure of each interior angle is approximately equal to 128.57 degrees. The equal sector chords form the sides of the required regular polygon. You can draw a square. One may think at first that one can construct an infinite number of regular polyhedra in three-dimensions, just as we could construct an infinite number of regular polygons in .
So each angle of a regular triangle is 60 degrees (180/3), each angle of a regular pentagon is 108 degrees (540/5) and each angle of a 7-gon (heptagon) is 128.57 degrees.
