It is: 180-interior angle = exterior angle
To work out the angle of any 'perfect shape' you use this formula: interior angle =((number of sides - 2) x 180)/ number of sides for an octagon: interior angle =((8-2) x 180 )/ 8 = 135 degrees
Each exterior angle 45 degrees Each interior angle 135 degrees
Interior and adjacent exterior angles form a straight line so exterior angle = 180 - interior angle. If you are satisfied with this reply please consider awarding a Recommended Point to the responder.

If each interior angle is 178 degrees then the regular polygon will have 180 sides.

Yes it does. Good work!
If the polygon has n sides (or vertices) each exterior angle is 360/n. Each interior angle = 180 - exterior angle = 180 - 360/n
Interior and adjacent exterior angles form a straight line so exterior angle = 180 - interior angle. If you are satisfied with this reply please consider awarding a Recommended Point to the responder.
IN a building context it the fame work for buildings(wooden exteria walls) and internal wall sections

(360) / (180 - n) n= interior angle in this case it will work like this: 360/(180-120) 360/(60) 6, so the number of sides is six.
To work out the interior angle use this formula(n - 2)*180/nwhere n is the number of sidesso for an 18 sided shape it would be(18-2)*180/18 = 160.
The sum of the interior angles of a polygon of n sides is 180o * (n-2). For a regular nonagon (9 sides), the sum is (9 - 2) * 180o = 1260o, so each interior angle is 1260o / 9 = 140o. The exterior angle is the supplement of the interior angle: 180o - 140o = 40o.
