If a circle is one, how many is an octagon?
Find the number of sides of the closed polygon
If a circle is one then an octagon is eight because the number here is denoting the number of sides and since the circle is
a closed curved polygon, it has only one side without any vertices. An octagon, on the other hand, has eight sides due to its eight connected vertices.
Hence, if a circle is one then an octagon is eight.
