Question

The sum of interior angles of
regular
polygon is thrice
the sum of its exterior
аngle. Find the no of
sides.
​

Answer 1

Since the sum of the interior angles is thrice the sum of the exterior angles, the sum of the interior angles is equal to 360*3= 1080. Since the sum of interior angles of a polygon = (n-2)*180 where n is the number of sides, (n-2)*180=1080, n = 8, therefore the polygon is an octagon.....!!

Answer 2

Answer:

Since the sum of the interior angles is thrice the sum of the exterior angles, the sum of the interior angles is equal to 360*3= 1080. Since the sum of interior angles of a polygon = (n-2)*180 where n is the number of sides, (n-2)*180=1080, n = 8, therefore the polygon is an octagon.
