A compass and straight edge are used to create a polygon but do not limit the number of sides of the polygon created. You have to decide that separately, then use the compass and straight edge to make what you decide on.
I'm not entirely sure what you are meaning to ask unless you simply aren't sure of the definitions of each. The circumference of a circle is the length of the entire edge of a circle. The perimeter of a polygon is the length of the entire edge of a polygon combined.
vertex
With a straight edge and a pencil is the easiest way
What is the special name for the segment that connects the center of a regular polygon to an outer edge to form the height of a triangle

3 or more sides
yes it can, in fact a polygon can have any amount of sides.. just some don't have names. a polygon is a polygon as long as the lines close at an edge, its a polygon.

It is called a side or edge.
An icosagon has no edges because it is a 20 sided polygon

It is an apothem line that connects the center of a polygon to the center of an outer side.

An edge is a straight line as part of a polygon. It can also be the straight line joining two faces of a solid which has polygonal faces.
