Step-by-step explanation:
Sum of interior angles of a polygon =(n−2)×180°
Sum of exterior angles of a regular polygon =360°
According to the question....
sum of the outer angles of polygon = twice the sum of the
inner angle
360° = 2×((n−2)×180°)
or
or 2×((n−2)×180°) = 360°
or (n−2)×180° = 360°/2
or ( n-2)×180° = 180°
or n-2 = 1
n =3
so side of polygon is 3...means it is a triangle.
sum of outer angle is equal to the sum of inner angle when it is a quadrilateral...
both have sum of angles =360..
HOPE thats ur que. and its solution..
