Do internal angles of regular and irregular polygons always equal 360 degrees?

No, the sum of internal angles of polygons is represented by the equation 180(n-2) where n is the number of sides. The sum of the external angles, however, does always equal to 360 degrees.

No way. All polygons have the same sum of exterior angles.You need the sum of interior angles.


How do you make a working model of math?

you can make a working model of any polygons. first,draw any polygons (triangle,pentagon,hexagon etc....)and also draw its interior angles and exterior angles (note the polygons sum of the angles). then cut its exterior angles.then bring the all exterior angles(after the cut) togather.now you can make a circle. its means , the sum of the exteriorangles of any polygon =sum of the angles of a circle (360 degree = 360 degree)
