The only number that stays the same for the angles of all polygons is that the sum of the exterior angles is 360degree.
360degree ÷side of exterior angle=no. Of side
=》360÷no. Of side=side of exterior angle
=》interior angle 168-》exterior angle
180-168
=12
=》360÷12
=》》30sides

if each interior angle is 168
than exterior angle is 180 -168 =12
number of sides =360/12
= 30
because total of exterior angle is 360
than exterior angle is 180 -168 =12
number of sides =360/12
= 30
because total of exterior angle is 360
