Interior angles of a regular 18 gon (octdecagon) are 160o.
Only when it is a regular polygon that all interior angles are of equal measure
1350
If you mean a regular pentagon then each of its 5 interior angles measures 108 degrees
The interior angles of a regular octagon are 135o each.
Each interior angle measures 177.12 degrees
this depends on what type of polygon it is.. if it is a regular triangle, then all interior angles measure up to 180 degrees. So, a triangles interior angles would measure 60 degrees each.
Each of the 6 interior angles is 120 degrees in a hexagon.
No, it's not.
Each interior angle measures 144 degrees
Each interior angle measures 140 degrees.
It will be an equilateral triangle and each interior angles measure 60 degrees.
