False. They can only be straight line segments: there cannot be any curved line segments.
It is called a polygon. * * * * * Yes, but only if they are straight line segments. And, in that case, the shape is a quadrilateral.
a straight or curved continuous extent of length without breadth.

A polygon, but only if all the line segments are coplanar.
False. They can only be straight line segments: there cannot be any curved line segments.
A circle is composed by an infinite sequence of straight line segments, while a polygon has a finite sequence of straight line segments.
A polygon is made up only of line segments. If a 2-dimensional closed figure has even one curve line, then it is not a polygon.
A triangle, but only if the line segments are straight.
It is called a polygon. * * * * * Yes, but only if they are straight line segments. And, in that case, the shape is a quadrilateral.
No, they could only form a straight line.
No, the "U" shape is not a polygon. Polygons are closed figures made up only of line segments. The "U" shape includes a curved section, and is usually not a closed figure.
Two: a straight line and a curved line.
a straight or curved continuous extent of length without breadth.
A bell is a shape, but not a polygon. Polygons are constructed only from straight line segments, they do not contain curves (a circle is not a polygon either, unless you imagine it as being composed of infinitely many line segments, each of which is infinitely short).
what of a triangle has three line segments that intersect only at their endpoints
