If there is regular polygon(having equal sides), then perimeter is L*N where L is length of side and N is no. of sides. If polygon is not regular then may Perimeter is equal to sum of all sides, if size of each side is known.
360/exterior angle = number of sides of a regular polygon
If its a regular polygon then its 147 degrees.

equation for any regular polygon when n = number of sides: 180(n-2)/n
The polygon is a Quadrilateral.
Each interior angle of the regular 8 sided octagon measures 135 degrees
I assume you mean a polygon inscribed in a circle. It is regular if all its sides and angles are equal.
'Regular' means that all the sides on the polygon are the same length and all angles are the same size. On an irregular polygon, the sides can be different lengths and angles can be different sizes.
A 6 sided hexagon polygon can be regular or irregular.
If the polygon is a regular polygon then all interior angels are equal to 180-(360/no of sides of the polygon)
its a not regular polygon
