circle
The circumference is the distance around a closed curve. It is used to mean the perimeter of a circle.The circumference is the distance around a closed curve (i.e. a circle).
Yes, a circle is a closed curve: its starting and ending points are the same. (any arbitrary point) Yes, it is a closed plane curve (two-dimensional line). A circle has a constant arc curvature, as compared to obloid or elliptical closed curves.
a poloygon that does not curve or cross and is closed
Technically, yes.
simple curve is a curve which doesnot cross itself,it neednot be closed....... but a simple closed curve is a curve which is simple and also closed. every simple closed curve is a simple curve but not vice versa.
No, it is not.

Ellipse and curve! apex
An ellipse is a conic section which is a closed curve. A circle is a special case of an ellipse.
