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 of the 6 interior angles is 120 degrees in a hexagon.
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.
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.
