A polygon.
Not at all sure about "indiffernt cuver" but indifference curves will not cross.
If it is a closed figure which doesn't cross over itself (like a bowtie looking figure), then it is called a polygon.
No. Some of the classic curves studied by mathematicians: ellipses, hyperbola are cross sections of a cone taken at an angle.
If none of the sides ever cross each other, there cannot be a closed plane figure.
a poloygon that does not curve or cross and is closed
Polygon
Because a polygon is a closed figure with straight lines that do not cross, and that's what a hexagon has.
They are closed plane figures bounded by straight lines that do not cross each other.
It must be a plane figure. It must be closed. It must be bounded by straight lines. These straight lines must not cross one another.

If "colsed" is meant to be "closed", and if the figure is planar (flat), and if the sides of the figure do not cross, then it is a polygon. But answer to the question could include shapes such as stars (pentagrams) which are not polygons..
If it is a closed figure which doesn't cross over itself (like a bowtie looking figure), then it is called a polygon.
They're not allowed to have curves, cross itself, and not connect.
i guess cross doesnt have an effect on ghost...
no because if crossed they different level of satisfaction
Straight lines that never cross are called parallel lines.
Yes it is leagal to cross a closes highway
