Q.5) The sum of the interior angles of a polygon is twice the sum of its exterior angles. How

many sides

does the polygon have?

• as sum of interior angles= (n-2)180 & sum of external angles= 360 so equating both we get
  (n-2)180= 2*360
  >180n= 720+360
  >180n= 1080
  >n=6 so , the polygon has 6 sides
