18 sides
If each interior angle is 160 degrees then it will have 18 sides
18 sides
360/18 = 20 sides
An octadecagon - 18 sides
Providing that it is a regular 18 sided polygon each interior angle measures 160 degrees.
If the exterior angle is 18 degrees then it will have 20 sides.
The sum of the exterior angles of any polygon is 360 degrees. If each angle is 20 degrees, there must be 360/20 = 18 such angles. 18 angles means 18 sides so it is an 18-sided polygon.
18 sides
If you mean a polygon with equal exterior angles of 18 degrees then it will have 360/18 = 20 sides.
If those are exterior angles, the exterior angles of any polygon add up to 360. That would be 18 sides.
